Database error - PLEASE HELP!

[Chachacha]

Ok so I've done NOTHING with my forum. I went to bed last night and everything was fine. I get up this morning and I get a white page with "Database Error" on it. I looked at the page source for that page and this is what it shows...



Database error in vBulletin :

Invalid SQL:

SELECT *
FROM datastore
WHERE title IN ('','options','bitfields','attachmentcache','forum cache','usergroupcache','stylecache','languagecach e','products','pluginlist','cron','profilefield',' adv_modules','adv_portal_opts','adv_portal_page',' adv_portal_tpst','attachmentcache','bbcodecache',' birthdaycache','eventcache','iconcache','maxlogged in','rankphp','smiliecache','userstats');

MySQL Error : Can't find file: './******/datastore.frm' (errno: 13)
Error Number : 1017
Date : Monday, November 3rd 2008 @ 05:56:04 AM
Script : ******
Referrer :
IP Address : ********

Classname : vB_Database



What can I do to fix this besides a backup? I have a fairly large forum and i need it back up asap! Please help.

Have you tried running repair/optimize on the tables yet? errno: 13 is permission denied. Have you checked with your host to see if they have done something?

actually this error is related to your server, not vBulletin... you will have to ask your webmaster to check the integrity of your database -- if you are not aware of the error you may not be suitable to correct it... ask for help!
