When I logged in as Admin of my site to moderate some product changes (specifically adding a new DNN role at purchase of a specific product), I was shown the error below. Note that moderating changes had worked before, no issues. 

As a side note, I duplicated the product pending changes and deleted the original one, so it appears I am okay from a customer side but I have lost this moderation ability. Thanks for your help!

Hi Patrick

So if you have deleted the product does this mean you are unable to get the site to generate the exception any more? Ideally we'd have given you a debug build and got you to generate the exception to get a line number for the issue.

Are you see any other issues?

Regards

Mark
