I am running into an issue when performing an update http://<MYWEBSITE>/Install/install.aspx?mode=upgrade   I am getting a message that says the upgrade is successful, see below, but when I click on the link to goto mywebsite, I get the following error and the URL I get back is http://<MYWEBSITE>/Default.aspx?tabid=72&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0 with the error display below.  I am new to the update process and am just starting to role this out. 

 Thanks!

Upgrade Complete

I attempted that because I read on a simlar post the suggestion and still no luck.  At the top of the web.config fille I added a rem comment ie <!-- FORCERELOAD --> and saved the web.config and still no luck.

 I have some more clues. Looking through the DNN EventLog table comes up with an entry that includes:
