New Post: Error when go to Settings for module on web page

I have set up a module development site for our website and am using Visual Studio 2012 and the Christoc templates - I believe they are version 2.5 - not sure if there is somewhere in the download or templates where I can confirm this. I was able to create the module, build it without errors, and install it successfully on my website and it did what I wanted it to do. Next I was going to change some of the standard module settings and one of the settings that I set up for the module. However when I click on 'settings' I get a 500 error. I went back into the code and commented out all of the code on the settings.ascx and settings.ascx.cs pages , rebuilt the module and reinstalled. Module still works and clicking on Settings still throws a 500 error.

I would appreciate any ideas that anyone has on where to look for what is causing the problem.
