This error seems to be connected to the webservicesettings element. If I remove that element, the page loads, but when I include, it fails.

Hello Jonathan,

Check the following forum thread which discussed similar scenario.

Hmm, yeh, removing the webservice elements, or setting enableadvancedform = false gets rid of the error, but I need both of these setup. Strange cause this was working before, but something in my project must have changed. Anybody else have this issue?

Hello,

Could you share what is the version of our controls that you are using?
Also, could you verify that this behavior is the same with the latest version of our controls?
