I've uploaded the files, but my browser says file not found. Why is that?

There are a few possible reasons for this error.

1. You have uploaded your files to the wrong directory. The directory where you must upload your files from the File manager or FTP looks like this: /www/mydomainname.com
   
   If you uploaded your files to the root of /www/ then this is the problem. You have to move the files from /www/ it into the directory of your website.
2. You have changed the path of your subdomain/domain and set a wrong directory.
   
   From the section Subdomain Manager -> Edit -> Path in the Control Panel, verify that you have set a correct and valid path (directory) for your subdomain.
   The path must look like this: /www/mydomainname.com
   
   If you have deleted the directory of your subdomain/domain, you have to create it again and move/upload the files there.
   
   If you only have set the wrong path of your subdomain, just set the correct path and it will work.
   
   Please note: If you update your path, 10 minutes are required for changes to apply.

Can I use the same directory for multiple subdomains?

Yes. You can use one directory for more than one subdomain. When you create or edit a subdomain you simply set the path to any of the directories available in your account on the server.

What is a subdomain?

In DNS hierarchy, a subdomain is a domain that is part of a higher level domain name. DNS hierarchy consists of the root-level domain at the top, underneath are the top-level domains, followed by second-level domains and finally subdomains. For example, in the subdomain name name.domain.com, name is a subdomain of the parrent second-level domain domain.com. In fact, the 'www' is also a subdomain of your domain name and is created by default. Both www.my-best-domain.com and my-best-domain.com will open your website.

Every subdomain points to a directory on the server. The name of the directory can be your domain name (yourdomain.com or yourdomain.com) or a subdomain address - e.g. name.domain.com. Different subdomains can point to the same directory.

How to set up a working subdomain?

First, go to the Subdomain Manager section of the Control Panel.

To add a new subdomain, you must have an active domain in your account. Here's what you will have to fill in the form:

Subdomain: Choose a name and write it in the prefix field. In case you have multiple domains in your account, choose the domain using the drop-down menu.
IP Address: In case you have purchased a dedicated IP, you may set it for the new subdomain from the drop-down menu. Otherwise, the default server IP will be selected.
Path: If you leave it blank, a default folder will be automatically created, labeled after the subdomain name you have specified above. You may choose a different folder that already exists by using the button on the right.
Error 404 page: If you leave it blank, the Apache's web server default page will be used. You may type in the URL (e.g. http://www.my-best-domain.com/404.html) of your own custom page, which you'd like to appear when a visitor requests a wrong or non-existing page/folder within the current subdomain.
Activate FrontPage Extensions: Check the box next to this option to activate FrontPage Extensions (FPE) for this subdomain, or leave it blank to disable FPE.
Activate access & error logs: To enable or disable the saving of access and error logs for this subdomain, just check or un-check this option.
Secure Socket Layer (SSL): Use this option if you would like to activate SSL for this subdomain. To use SSL you must first order a dedicated IP address from the Add Services section, then generate a SSL certificate. For more information regarding SSL, please contact support.

When ready, click the Add Subdomain button.

Note: You will have to wait approximately 10 minutes for the changes to take effect before you can use your new subdomain.
