==I can't access G2 from my vHost or subdomain, what's wrong?==
Probably you use the G2's short URLs which are generated by G2's URL rewrite module. If you have a .htaccess file in your gallery2 directory, this is the case.
You have two choices:
* Either access G2 only with one of the vHosts / (sub-)domains or
* Don't use the URL rewrite module
And if you decide to use the URL rewrite module, you have to activate the module while accessing it from the correct / chosen vHost / (sub-)domain. To change it, access G2 from the URL which you used to install it. Deactivate and uninstall the URL rewrite module. Then access it from the URL that you prefer and install and activate the rewrite module again.

Technical background: When using the URL rewrite module, G2 has to store the path to the G2 main.php file in the database and in the .htaccess file. E.g. if the 'normal' URL is {{exampleurl|/gallery2}} it stores '/gallery2' in the .htaccess file and in the database. If you then want to access it from a vHost that points directly to the gallery2 directory, e.g. ''<nowiki>http://mygallery.com/</nowiki>'', then it would generate wrong redirects and URLs since G2 still assumes it is installed in a subdirectory '/gallery2' of this domain. You may notice that this doesn't apply to two different domains which have the same webroot.
