The plugin works with your config.
See if you have installed - ImageLibrary.

all my other plugins are working fine, i have imagelibrary running

Plugin work. Your config work.
I can't help you with anything else, because I don't see what you have there and I don't have access to the server.

apparently i dont get the error anymore... very strange

Magic.
