When I went there I got this message although I'm the Admin, the only one actually:
It is in your includes/config.php file..edit it and add your userid number(admin user) to the part Ozzy mentioned and you will be able to run query. Make sure you are an admin though with full permission.
I was going to do it as I was on his site earlier but I thought it was simple enough that he could learn it himself with the instructions posted here. It would be beneficial to at least learn the settings. Glad it's all set though.
