We give unlimited disk space for free. Immediately after registration you get 400 Mb of disk space, but the longer you stay with us, the greater amount of Mb is automatically added.

No, we do not allow to use the scripts as the majority (90 % +) of free-of-charge scripts are written by beginners in programming who are still learning to code, and these scripts are unsafe for the servers and therefore for users’ sites.
We make up for the impossibility to install the scripts with a lot of services, by means of which everyone can make a unique site of any level of complexity.

Yes, you can. There is the capability to upload your files both via FTP and File Manager.

Any! To attach a domain correctly, you should just follow the instructions which are given in your Control Panel. Thus your site will be accessible both by your domain and by the initial ucoz domain.

First attach you personal domain, e.g. "mysite.com", in the section "Domain attachment" of the Control Panel (Method 2, domain transfer by DNS). Afterwards you'll be able to adjust MX records and create various e-mail accounts in your domain with the help of various mail services, e.g. Gmail.com (Google Mail).

You can find instructions on how to create mail boxes in your domain with the help of Gmail.com in the Control Panel, "Domain attachment" section.


The maximum permitted size of a file for uploading on a uCoz.com server is 15 Mb. This size increases if you buy additional disk space from uCoz.

Yes, you can. You should only specify the link to the uCoz module which you want to use on your site.

For example: http://www.your_site.ucoz.com/forum/


Go to your Control Panel - Common settings. Find the option "When opening the main page, redirect to:" and select the necessary module from the drop-down list.

Attention! Redirection to other sites of uCoz system is not possible.


We are constantly improving the system by adding new modules or updating the existing ones.

Yes, it is possible. Find the link "File Manager" in the Control Panel and click it. You will see a list of all files, uploaded to the server. To upload a new file from your computer click "Browse", find the necessary file, select it and click "Open".
Then click the button "Upload file". Loading should start, and as soon as it has finished a name of your file will appear on the list of files.

Pay attention to the maximum size of an uploaded file - 15 Mbytes.

You can also upload files to the server using any FTP client (for example, CuteFTP). You can find the details of FTP connection on the main page of your Control Panel, "FTP details" link at the top.


You can change them in "Common settings" section.

Probably that’s because you are using MyIE add-on that is full of errors. You need to update this add-on to the last version (now it is called Maxthon) or to use such browsers as IE, Firefox, Opera without any add-ons. Remember, if you can’t add something, that means that an error occurs on your side and you can solve it without our help.

You can ask all your questions about design customization in our support community forum.ucoz.com. You will find answers to almost all your questions while reading the forum.

In uCoz system the cleanings of inactive ("dead") sites are constantly running. A site is considered to be dead if no one visits it for 40 days. If you use .html files as your site, the visitors on the site are not taken into account and such sites are also removed in 40 days. According to the system rules you should use at least 1 content module (blog, news, catalogs, forum, guestbook etc.). If you need a simple static site constructed of html pages, uCoz is not what you need.

The system does not remove the sites at once, it marks them for removal (thus they do not work); the site has this status for the next 15 days and during this period registration of a site with the same address is impossible. While the site is being marked for removal, it is still possible to restore it. However we can restore only a site that contains sufficient amount of entries, we do not restore empty sites!

We do not carry any responsibility for your unwillingness to observe the elementary rules of our system.


Icon replacing is possible. You just have to upload your own icon to the root folder of your account (you can’t see it, after entering FTP you are already in it, and the same with the File Manager). The data for FTP connection are located on the main page of the Control Panel.

You can create your custom set of smileys in the section "Smileys Editor" (the link can be found on the main page of the Control Panel). After creating a set of smileys, it is necessary to specify in module settings that you want to use this set (just examine module settings).

Besides you can add your smileys to any of the existing sets. For this purpose you must create a folder named "sml" in the section "File Manager", and upload there any smileys. The amount of smileys should be not more than 200 pieces, all the smileys should have .gif extension, and such smileys would work only if BB-codes are enabled.


BB codes are one of the informal standards of text formatting, without the usage of HTML tags. We have replaced HTML tags by BB codes for the purposes of safety, as by means of using HTML tags a dishonest user can spoil the appearance of your pages, пуе important information stored in cookie files of your site visitors, and do other unpleasant actions.

It is possible, there are special $codes$ for this purpose. Control panel - "Customize Design". Investigate this section.

It is also possible to redirect visitors by means of META tags. You can read how to do this in HTML manuals.

You can upload any files, the size of which doesn't exceed 15Mb.

It is uCoz ad banner. It can be removed for a fee. You can do it through the Control Panel, "$" tab.

Control panel – "Customize Design". Choose a template, insert there any HTML code.

Yes, there is such capability. You can find the details for the establishing of FTP connection in the section "File Manager" of the Control Panel or on the main page of the Control Panel. Remember, for FTP to work you should confirm your e-mail and set FTP password.

It is impossible. But if you have your own domain you can attach it to the site for free (e.g.: http://www.yourdomain.com/).

The capability to use PHP scripts will never be planned. The matter is that by means of a 5-line script one can overload a server very strongly. We care about our users.

Certainly, you can upload your own robots.txt file using File Manager or FTP client. However we strongly recommend not to do this as the default robots.txt file is adjusted so that search engines could index your site the most qualitatively, i.e. Robots would see only the pages of your site that contain some information and would not see any technical pages (users’ login, registration of users, etc.).

Probable problems:

  • Cookies are not accepted (or blocked) by your browser or firewall. Adjust these programs and you will be able to log in.

  • Service for traffic economy ("Traffic Compressor") is used. When using this service all information is being archived and transmitted through another server. Therefore IP can change each time you update a page.

  • You have installed software which dynamically changes proxy address and therefore hides your real IP. It is necessary to turn off the program when working with the Control Panel or with your site as we use binding to IP address (it is a standard safety method).

  • Someone else is trying to work in the Control Panel simultaneously with you. As session is bound to IP address it is impossible to work from 2 different IP addresses simultaneously.


As a result of struggle with people who use the system to create doorways we temporarily block sites indexing by means of "robots.txt" file. Such blocking also helps not to pollute search engines with empty sites. You shouldn’t worry about that, blocking is automatically disabled in 30 days (it should be enough for you to fill the site so search engines could index it in the best way) or if the site is attended stably by some minimum number of visitors (exact values are not disclosed in order to prevent abusing).

Promotion of a site should start not with its addition to search engines (SE would find your site anyway), but with reading the section "Site Promotion" (the link is on the main page of the Control Panel).

Remember, we are also interested that your sites were interesting and popular, therefore EVERYTHING that we do, we do for your advantage.


It is possible, in spite of the fact that we do not support ".htaccess" file, we have enabled the opportunity to customize own page with the error #404 (file not found). To install your own page you should simply upload a file named "404.htm" to the root folder via FTP or File Manager (the link is on the main page of the Control Panel).

You can customize "404.htm" file as you want, it depends on your skills in HTML.

*root folder is the folder where you get immediately after entering File Manager.


We have thought of people, inexperienced in HTML. So you can replace necessary blocks on your site by pressing only 1 button. For this purpose you should enter the section "Design Customization" -> "Quick replacement".

Control panel-> Customize Design -> Site Menu Builder. You can customize on your site everything you need, all you have to do is just to examine the Control Panel.

Probably you haven’t investigated the Control Panel. All extra functions for design customization etc. are accessible for management from any page of the Control Panel and are located in the drop-down menu in the top left corner of the Control Panel.

The closer you investigate the control panel, the easier it will be to work with it.


If you have got such a trouble, even after the system has warned you about the importance of remembering the answer, you should contact Technical Support from your Control Panel -> "Help" tab. If you want to change your secret question/answer you can do this at Webtop -> Settings -> Profile Settings -> Security.


  • If the version of your browser is less than 5.5 for Internet Explorer or less than 8.0.1 for Opera - then install a new version.

  • If everything is ok with the version of your browser - then clear browser cache data. By the way, it is useful to do this periodically not only to solve the mentioned problem (e.g. IE does not save graphic data correctly if the cache is filled). To clear the cache in IE open its properties and press the button "Remove files". Attention - do not confuse temporary files with cookies (these are different things).

  • Do not use the services for traffic economy (like Traffic Compressor). These services have plenty of servers and for every other inquiry servers can give out different IP addresses (the least loaded server is selected). As IP address varies, the protection of binding to IP works and so the system logs you out.

  • Troubles with other programs are also possible. For example, firewall can block transfer of big posts (relevant for templates saving). You should try to find a source of a problem stage by stage (if all the previous points are fulfilled).

Yes, you can. You can attach any domain to your account in the section "Domain attachment" of the Control Panel. You can fully manage this domain, create subdomains and mail addresses like mail@mysite.com.

You can attach only one domain to one account.

You can create, for example, 3 accounts and attach a domain "MYSITE.COM" to the first one. Then, by means of domain management system, create 2 subdomains, e.g. "SITE1.MYSITE.COM" and "SITE2.MYSITE.COM". And then attach the created subdomains to the remaining two accounts.

In such a way you can create unlimited number of sites in your domain.


uCoz is the system for creating dynamic sites, that's why we have disabled uploading of files with .html, .htm and .shtml extensions via FTP. If you need to upload such file you can do it in the Control Panel in "File Manager" section.

If you have your whole site consisting of such files, then it is time to proceed to the next level of site creation, i.e. creation of dynamic sites. For this purpose examine the module "Page Editor". Here you can create unlimited number of pages and fill them with any information, at the same time the design of your site will be within 1 template only, which helps to quickly change the design. Content of dynamic pages is in the database, thus it is not bound to the design. You can manage page content both through the Control Panel and the site.


1. Create a backup copy of your project in the "Backup" section.
2. Download absolutely all files and databases of your site.
3. Employ a programmer or write yourself a script for converting databases into necessary format and distributing files among necessary folders.
