Aslam-0-Alikum All.
Friends i have problem.
Same days ago I install mybb by using auto software installer tools. 
And i was shift my vbulletin 3 forum to mybb 1.8 by using merge system 1.8 ,
We have dons't any issues but yesterday I was going to cleanup my hosting extra database.
And I deleted my old vbulletin 3 database and don't touch mybb database. 
By deleting vb3 database I have received error. 

MyBB has experienced an internal error and cannot continue.
Error Type:
MyBB Error (44)
Error Message:
MyBB was unable to load the SQL extension. Please contact the MyBB Group for support.
Please help me urjently.
How can i solve this issue?

check if this guidance helps.
if changing the database type doesn't help then change it back to earlier type & contact your web host and ask to fix it

Every thing is ok please tell me.

Once you merged vbulletin database to MyBB then you dont need vbulletin database .

No, once the data has been merged in, the old database will no longer be used for anything.

Edit: too slooooow

But when i delete old vb3 database my forum have been crashed?
