Well, i couldn't make a Dbase backup.
So i did it in the admin CP (SQL file)
next step i tried to extract it:
mysql -uUSERNAAM -p dbasenaam < /www/forums/vbulletin.sql
But it says: /www/forums/vbulletin.sql doesn't excists.
But, im not a n00b, I know where i stored it, and it really excists when i look with SSH in the folder.
Next step is i tried to add is via a SQLmanager, but instead of the Dbase name wich is stored in the SQL file, it creates a dbase: vbulletinsql
Next i tried is to change dbase name to vbulletinsql on localhost.
But also that won't work.
After trying that, I wanted to try it via SqlMyAdmin so i saw the Dbase, selected the SQL file on my harddisk and tried to import that one in the excisting EMPTY database. But i got a Import error after 15min of waiting.
I really dunnow what to do now
