This is still haunting me.
I now did the following:
I set up a complete new DNN 4.9 site. It runs on Win7/ IIS 7.5. All just standard setup. App Pool runs under .Net 2.0.50727 Integrated.
I logged in and everything works.
I update to 5.2.3 and guess what, same issues. Most linkbuttons don't work. Login and Register don't work. Simple http links do work.
So this proves it is not specific to my web site I want to upgrade. Not specific to any skin or module. The same problem exists with a 4.9 default DNN site upgraded to 5.2.3.
I found this in the DNN EventLog:

Any ideas?
