I am getting this error recently. Specifically - "There is a problem with the resource you are looking for, and it cannot be displayed." I run two copies of my site, greek-solutions.com and greek-solutions.com/dev which is the development section for testing. They run on separate application pools and have not had any issues. A few weeks ago the dev section started failing. The code on both should be exactly the same - not sure what my issue is. Does anyone know if any ways to troubleshoot this error? http://www.greek-solutions.com/dev/ is the specific page - but any of the pages in the directory get the error - even images.
