منتدى استراحات زايد - vBulletin 5 Beta 10 Upgrade Error

Hello. I have just upgraded from vBulletin 4.2.0 Patch Level 2 to vBulletin 5 Beta 10. When I was upgrading I got this error:

An error has occurred with your database. Please contact vBulletin Support for assistance.

Module: 500a23, Step 2 Database Error:1064

Query:

UPDATE setting SET
value = value |
WHERE varname = 'defaultregoptions'

I then pressed okay and it said aborted, I then refreshed and the upgrade continued.
The upgrade had then finished successfully .

I then went into the admincp and it says: "Could not find phrase 'after_upgrade_4112_update_sitekey'."
Not sure if that has anything to do with it or not.

In the error_log in my main forum root it says: [21-Sep-2012 19:29:39 UTC] PHP Warning: Cannot open 'extra/browscap.ini' for reading in Unknown on line 0

The problem is that when I got to my url the images don't display correctly and when I click on "Forums" in the tab it redicts to http://www.mydomain.com/# and when I manually go to http://www.mydomain.com/core/ it just gives a blank page. Blogs, Private Messages etc all work though. How can I resolve this issue?
