I see... Well, I'll keep investigating this. Thanks for your help, kh.

lol, yeah I know I wasn't any help. But probably someone else will have an idea.

Hey! At least you try to help me <.< that counts as something... So accept my thanks.

The exact database error will be emailed to the email you entered into your /includes/config.php file. So, go check that email and let us know what the exact error is that you are getting.

That IS the problem.
The config.php file has 2 emails. The one that is admin@arsmagnum.com, wich I dont have acces to, and the other one is my personal one. Wich I added in the config.php file after the crush, and I still haven't received any email.

It looks like if you put the forum in debug mode (add $config['Misc']['debug'] = 1; to config.php) then it should display the message.

Aaaaalright! so, now I see the source page and showes me this:

Database error in vBulletin :

The config.php file should only have ONE email. Please remove the other one and only enter your own.

I got the email and said this:

That is an error you would need to show your host to fix (if they will). Usually if you are on shared hosting, they only allow xx (think, small number) connections for your user.
