MyBB Community Forums

So, someone told me they can't register on my forum.
I tried registering myself and got this error:

MyBB has experienced an internal SQL error and cannot continue.

Did you mess with any settings?

What tab plug in are you using?

MyTabs by Ethan.
It seems that is making the problem. So after removing the plugin, it works.
Guys - what other tabs plugin can I use that DOESN'T mess up your entire forum?

you can use tabbed menu from labrocca, but you need to make some changes to be compatible with 1.8.
