I have a problem on my Development server.... On my local machine everything works....
This is the issue:
I have a Page that looks like this:
I figured it out. It was because of this in the Web.config
<requestLimits maxAllowedContentLength="1048576000" maxUrl="260" maxQueryString="25" />
It was the maxQueryString.
I have since removed both maxUrl and maxQueryString and it is all working now :)
just off the cuff, are you supposed to have two ? in the url ?
Im pretty sure you can only have one ? and separate the querystring parameters with &
so you should be using this shape
/Profile?id=Profile&id=E23CB58D-BDBC-4BE5-A27C-7E6518ED72B0
