after upgrading my localhost site to 6.0.0, there is this strange behaviour in the login page, which affects only the production site, and I was not able reproduce it on localhost.
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '<!DOCTYPE html PUBLI'.
The string being parsed is the full html source of the home page.
Server log shows this:
2011-08-06 14:21:02,502 [webs76][Thread:20][ERROR] DotNetNuke.HttpModules.Exceptions.ExceptionModule - Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.
at DotNetNuke.HttpModules.Exceptions.ExceptionModule. Request(Object s, EventArgs e)
Login is successful, I just have to manually close the popup.
Localhost and production have same files and database.
web.config only differs on connection string, and impersonation tag.
IIS 7.5 - administrative account
CAS Permissions: ReflectionPermission, WebPermission, AspNetHostingPermission
IIS 6.0 - impersonation (<identity impersonate="true" userName="xxx" password="yyy" />)
