Cause:

The Ultimate Survey web.config file is either cached or has improper settings.

Resolution:

1. Check the following values in your web.config file:

ApplicationURL - This setting should be the URL of your web server, e.g. http://www.prezzatech.com

AppicationRoot - This setting is the virtual path to your installation of UltimateSurvey, e.g. /UltimateSurvey

2. If updating these settings still does not solve the problem, take the following steps. First, rename your web.config file to web.config_bak. Refresh the page with the error, and a different error will occur. Next, rename the file back to web.config. This takes care of any caching problems, and the software will run.
