I installed XOOPS to my rootfolder.
After struggling with the installation, I finally made progress, and all things was just fine. I had to use a subdomain like mydomain.com.myhost.com during installation because the domain was not transferred yet.

Today my domaintransfer was ok. Thinking that mianfile.php holds the physical/virtual path changes where made there.

Orginal mainfile:
// XOOPS Virtual Path (URL)
// Virtual path to your main XOOPS directory WITHOUT trailing slash
// Example: define('XOOPS_URL', 'http://mydomian.85.seekdotnet.com');
define('XOOPS_URL', 'http://mydomain.85.seekdotnet.com');

After Changes:

// XOOPS Virtual Path (URL)
// Virtual path to your main XOOPS directory WITHOUT trailing slash
// Example: define('XOOPS_URL', 'http://mydomain.com');
define('XOOPS_URL', 'http://mydomian.com');

The physical path was left intouched, as there had been no changes to that.

When trying to go to mydomain.com/index.php I get the familliar log in box. However, using my username and password created during insatllation does not work.
I get an error saying:

Selected module does not exist!

What went wrong here? Could it be that I have tomake changes to more then the mainfile.php? And if so could people tell me what files needs to be changed?

Two possibilities to try here.

First make sure you empty the template_c and cache folder (smarty compiled files stored here could still be using your old path).

If that doesn't work try http://www.mydomain.com for the virtual path. I have heard of some problems when the "www" was omitted. Again clear the templates_c folder after the changes.

HTH.

Thx jd.
Actually I started with the cache folder, and after making a backup to be sure, I deleted the two files in that folder. When I checked login worked. So first I guess it tried to load the site from the cache folder, and when that did not contain any data it loaded mainfile.php.

Well good to see it all works now.

Thx again.
