Problem after installing on subdomain

[1303i]

I have a problem after installing the gallery on the subdomain. I can not create a category (and use other similar buttons on the toolbar), due to the fact that the path in the address bar isn't constructed correctly.
Subdomain is a folder on the main server. So the site "subdomain.site.com" is in folder "site.com/subdomain".
When I click "Create a category" in the toolbar of the gallery IExplorer shows the address "www.subdomain.site.com/subdomain/index.php?bla-bla-bla". That is the combined sub-domain name and path to folder of subdomain. I get an error 500 - view not found (phocagallerycs, html, phocagalleryView). All other components on the site are working properly.
How to correct address?

Hi, no idea what can be wrong there. Phoca Gallery doesn't create the links, they are created by Joomla! framework, so there should be not a problem

I've still not found a solution. All actions with the gallery i have to do through the mysql as buttons in the admin's part of the gallery give the wrong address and error.

Try adding the var $live_site variable in your configuration.php to suit your sub-domain. If the server is nor well configured for (sub-)domains without the "www." it can give problems with URL's. This is common on Plesk and some older cPanel servers.

I have it written a long time. It does not help.
