[*SOLVED*]This error is caused by an incompatibility with another 3rd party plugin.
Someone else brought this to my attention after installing VbSSO, but new users cannot register and it throws a databases error.
*update* The new user actually is created, however there seem to be missing/broken tables for that user. Upon logging in there are more database errors before the forums can be accessed.

Should there be a value at the end of the SQL line before the 'LIMIT 1?'
Or can SELECT TOP 1 * be used instead of LIMIT all together?

Oh and I'm running SQL version 5.1.63, thanks.
