'Exception occurred in UpdateUIList Value does not fall within the expected range.' error

Feb 3, 2014 at 6:32 PM
If I can get it configured correctly, I am sure it is a 4- to 5-star application. At the moment, however, the only thing I find in my logs is:

Processing site: http://server_name/ **** Exception occurred in UpdateUIList Value does not fall within the expected range.

I haven't been able to correct it yet. Any advice?
