XF 1.5 Upgrading throws an error!

[NeoCHI]

While updating one of my forums from 1.4.x (forget exactly which version it was) to 1.5.1 I got the following error:


Server Error

I upgraded like 3 other forums without issues...what's wrong with this one?

Looks like a file problem. Make sure that file exists (library/XenForo/Model/AdminTemplate.php). Also make sure the permissions on that file are appropriate. Depending on how your server is configured, PHP files are usually 644 and directories are 755.
