can't use adminCP

[rhondajean]

I hope someone can help me. My forum is working well but when I tried to log into the admin CP, it loads the side bar but gives me this message instead of the normal:

Database error in vBulletin 4.0.0:

Invalid SQL:
SELECT SUM(filesize) AS size FROM filedata;

MySQL Error : Table './downtoe4_forum/filedata' is marked as crashed and last (automatic?) repair failed

Repair the table filedata via a tool like phpMyAdmin (available though most server control panels). Or, upload tools.php to your admincp and repair the database tables that way.

Thanks Lynne. I'll have to wait for a friend to help me do that. I'll come back and let you know how it goes. I appreciate your help.

Lynne, how do we repair the tables? We have the tools but we're not sure what to do.

If you don't know how to use phpMyAdmin to repair tables, I suggest you contact your host.
