I just upgraded a dotnetnuke site (to 06.02.06) and am now receiving a pop-up that says "authentication required" when I navigate through pages on the site.
When I did the upgrade I simply copied the upgrade files on top of the files in the current application directory. When the upgrade ran it said that everything was successful and in general everything on the site works fine, but anytime I navigate to another page that pop-up happens.
I've upgraded using the same methods before and haven't run into this problem so am not sure what happened. I'm assuming that the permissions on one of the files is incorrect, but don't know how to determine which one or what might have happened.
I am running IIS v6 on windows 2003 r2 server.
Any help is appreciated.
