Everything seems to be working perfect with the portal and functioning great except one thing, I dont have the original prosilver enabled as I am not using it and when ever I try to change a setting in the ACP I get the error below but the setting will change and still work just fine. What could be the cause of this?

I have another forum running 1.0.6 without this error on a prosilver based theme and I cant seem to figure it out.
The web site is at a somewhat temp location while we put it all together but you can view it here - http://www.hippie459mn.com/mnmudboggers
Any help would be great.
