Unistalling Mods
 

I was previously using 3.8.5, and upgraded to 4.0.

I am having the following errors while uninstalling mods as they are conflicting with my shoutbox.

Database error in vBulletin 4.0.0:

Invalid SQL:
ALTER TABLE VBpost DROP COLUMN mh_pbc_colorschemeid;

MySQL Error : Can't DROP 'mh_pbc_colorschemeid'; check that column/key exists
Error Number : 1091

Any help would be really appreciated. Thanks in advance.

The information is here MySQL Error : Can't DROP 'mh_pbc_colorschemeid'; check that column/key exists

So the uninstaller can't run 'cause these tables don't exist, so try making new tables with empty data via phpMyAdmin, that will allow the uninstaller to run.

Disable all hooks via config.php then remove them via admincp...

Don't forget all the files too!
