XF 1.2 1.1.5 to 1.2.2 blank page on /install


Well-known member
I uploaded the files (overwritten) and during the upload of files the forum went blank - now that files are uploaded I access our /install and the page just pulls up a blank page.

Any ideas?

A ticket was submitted for this. It actually displayed a server error. When display_errors was forced to on, it said that XenForo_Application didn't exist -- the content in XenForo/Application.php actually had the class definition for XenForo_ControllerAdmin_Application.

So the recommendation was to reupload files.
