forum hacked ??
 

when i woke up my forum was down it said database error so i went onto the server the database was still there but when i clicked on the database there was no tables inside it do you think my server was hacked and all the tabled was deleted ??

ask ur host if they have a full cpanel backup n to restore it

Why do so many people rely on the host for backups? You should back your server up yourself regularly, at least once a week. I have lots of content added to my forum every day, so my server is backed up every night at midnight to minimise loss of content should the unthinkable happen.

i back my database up every night so i haven't lost the database i just found it weird the database just disappearing over night

It could be down to an issue with your host then, raise a support ticket ask them if they have an explanation for it if not ask them to check the logs to check what IP's have accessed cPanel or PHPMyAdmin, you may also want to get your passwords changed.
