Im not sure I understand exactly what the fix is. The download on that site is the Mysq.Data.dll I allready have installed and placed in the bin-folder of my site.

The thread isnt really up to date either so maybe its the ordinary connector but an early version? Anyway I grabbed it and replaced my old Mysql.data with it.
Same error.
 

Or is the fix to add those lines of code in web.config? They even mentioned to add some lines into mashine.config, and how should I do that when its not a deticated server.

 
Please someone help me out here, feels like im the first one to try get this mysql-thing working.
