MySQL error question (not a dolphin bug)

My provider upgraded my cpanel on my machine and since then everytime dolphin access mysql I get this error:  Mysql error:
Can't create/write to file '/tmp/#sql_97c_0.MYI' (Errcode: 13)

I tried to change permissions in the site's tmp folder to no avial.  Is the tmp file referenced above the root tmp file or a MySQL tmp file?  Any suggestions would be useful thank you!

Hello!

See this link from official site http://dev.mysql.com/doc/refman/5.0/en/cannot-create.html

Thanks for the info Kane.  It didn't work, whatever my hosting company did when they upgraded the server royally screwed mysql and they just got it working again.
