Basically, I tried everything I know how to do and need assistance.
I was forced to do a hasty server move in the last few days and now the vbulletin section of my website after restoring the database and files are returning blank/white pages.
I believe there are some offending files that are creating the errors (actually there are no signs of errors, no 403, 404, etc, ), and get this site functional again.
Files I have are an exact backup of the previous public_html folder on the old server.
I also have the 4.2.0 upload files fresh from Vbulletin which I've uploaded and did not change anything.
Something interesting to note is that the ADMINCP directory works, but the main pages for visitors do not. Also when I log in to the admincp, then visit the forum pages, I can see pages as if nothing is wrong. So there might be a problem, somewhere in the permissions for when a unregistered/not logged in user accessing the site.
I know it's not a server/[login to view URL] issue because I was able to install a fresh copy of Vbulletin and it works perfectly, but I don't need a new copy 4.2.2, this was just a test, I need the old copy version 4.2.0 back and running again.
