[Plugin: Add Link to Facebook] Eror code 324

When i try to save changes in the additional settings section. I get the same eror code 324 every time and a message that “the client wont transmit data”

I wonder wether that is a problem from my host or if it is something else?

I am a newbie, if the question are stupid, i do apologize 😉
