I upgraded 2 sites from DNN 7.2.2 to DNN 7.3 - 1 site worked fine but main main www.pokerdiy.com site is as dead as a doornail.
There were no errors in the upgrade script but when you navigate to it it says "
The page cannot be displayed because an internal server error has occurred."
I have downloaded the logs from Azure and it looks like it's something to do with URL Rewriting:
Detailed Error Information:
|Requested URL|| http://pokerdiy:80/|
|Physical Path|| D:\home\site\wwwroot|
|Logon Method|| Anonymous|
|Logon User|| Anonymous|
However, I can't figure out the problem - any tips on how to debug this please?
