Forum Upgrade Error On Fresh Install

[محروم.كوم]

Hi peeps

I have been trying to upgrade my forum from 3.8.4 to 4.0.1 for a while now with no success I keep getting database errors.

So I decided to create a fresh install of 3.8.4 with a nice shiny new database and then proceeded straight to the upgrade to 4.0.1 BUT I still get an error!

This is the error I get around step 5

Code:
Database error in vBulletin 3.8.4:

Invalid SQL:
UPDATE forumuser SET options = options |;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

Hopefully someone with abit more knowhow than me will see this and know what my problem is straight away. I just dont understand why I would be getting errors on a completely clean install and database. __DEFINE_LIKE_SHARE__
