I need some help with an SQL error please

I'm getting this error:

Invalid SQL: SELECT style.title, user.styleid, COUNT(*) AS count FROM user LEFT JOIN style USING (styleid) WHERE style.styleid IS NOT NULL AND style.userselect=1 GROUP BY user.styleid
mysql error: Got error 12 from table handler

installed hacks:
Style select on index page
quick reply
Mod/admin logger

Version:
2.3.0

I'm pretty sure it's the style select hack but I'm not sure what the problem could be. I read the support thread for the hack but didn't come up with anything. Any help would be great.

thanks

MySQL needs more memory. Ask your host to fix my.cnf for more memory allocation.
