[InF3RNo]

Hello, I'm receiving each 5 minutes emails from the forum I installed in a website that's now closed. The message is something like this:

--------------------------------------------------
Subject: vBulletin Database error

Database error in vBulletin :

Cannot use database inf3rnal_forum

MySQL Error : Access denied for user 'inf3rnal'@'localhost' to database 'inf3rnal_forum'

And they're coming each day non-stop making my inbox full of mails of this kind, what can I do? Should I contact the people I contracted the website to tell them if there's any data they didn't deleted when they closed the site or something or it's something different?

Thanks,
InF3RNo.

(ok it's solved now, it was FTP issue that the people I contracted the site didn't delete everything or something like that)

So the website is closed and no longer in use?

Yes, anyways it's solved now, I had to contact the place where I contrated the domain and they did something to solve it.

Thanks anyways.
