Nothing but white screens

[zaroba]

First, I kept getting an error message on my forum:
Warning: Illegal string offset 'name' in [path]/includes/functions.php on line 6845

Did a google search on this error and somebody else that was getting it that was using PHP 5.4. A reply to the post said that VB4 doesn't use PHP5.4 and the person should switch to PHP 5.3 and see if the error vanishes.

My site was set to use PHP 5.4 so I switched it to PHP 5.3.
Not only did the error vanish, but so did the rest of the forum. lol

Now there is nothing but white screens.
Checked in the Index.php and it looks correct.
Webhost error logs show no PHP errors.
Tried switching it back to PHP 5.4 and there was no change.

read the topic at https://www.vbulletin.com/docs/html/blank_pages and did all I could do (stuff not doesn't require accessing and navigating the admin panel), but none of that worked.

Anybody have any ideas?
