Database bizarre error

Well, it can be anything like:

– Corrupted tables
– Corrupted indexes
– Values replaced incorrectly when you performed SQL replace using a text editor(if it was done)

and so on, too much variables. It’s best to contact your host support to look into the problem for you.

Personally never seen this, but you can fix it from Phpmyadmin. If you don’t have access to it, then this might be your solution:

Make sure to backup first, before trying that.
