Site down - user database error

[BonsaiNut]

Went off on vacation and wouldn't you know, my site crashed while I was away. Problem with my user DB - I keep getting spammed with errors any time someone tries to login to the site. I cannot log into the site myself, and cannot access the AdminCP. Here is the error I get when I try to login to the AdminCP:

Database error in vBulletin 3.6.2:

Invalid SQL:
INSERT INTO cpsession (userid, hash, dateline) VALUES (X, 'XXXXXXXXX', XXXXXXXXX);

MySQL Error : Access denied for user: 'XXXXX' to database 'XXXXX'
Error Number : 1044

Any help?

Why would this suddenly occur when I have been running the site successfully for 9 months now, and I am the only one with ADMIN permissions and I was out of town?

Well, looks like you are not the only one with access now.

Have you tried resetting the password via cpanel or whm?

I might as well post this since it might help someone else with the same issue.

The problem is not on my side - it is on my host's side. Little did I know that in addition to the web site size limit, I also had a mySQL database size limit. So even though I was well within my web site and bandwidth limits, my host cut off access to the database because it had exceeded the limit of (gasp!) 100MB.

Time to find a new host...
