I need help with an error that has cropped up after my 4.8 upgrade was finished and tested working. I went through and upgraded all the modules signed in as host, and had no problems with anything, logging in and out repeatedly.
I'd love a little help on this one, as NONE of my portals are accessible right now, except for the front pages (Which run fine, by the way).
Now suddenly I am getting the following error message:
Server Error in '/' Application.
Cannot redirect after HTTP headers have been sent.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
