MyBB Community Forums

I deleted the backup directory of my forum. Now i can not able to backup databases through Database Backup option. When i click then error messages appear "mybb internal error contact mybb"

Then re-add the backup directory it is needed to take a backup.

Although in saying that I advise against keeping this enabled I delete the ability to take backups from the ACP and use server software to take the backups

I added backups directory but same error.
What should i do now...?
