I was updating a site from 4.9.1 to 4.10.1 and ran into a big issue. I cannot access anything on the backend or the frontend of the site now. I only get this:

On this episode of blowing up your Umbraco install...
The problems I had after updating were a result of tumbling down the wrong rabbit hole. Ends up I was trying to use two different versions of log4net (one in a control I wrote, and one that comes with the new version of Umbraco) and that was causing all sorts of issues. Going through the update per the instructions and merging the config changes did the trick.

Thanks.
I had overwritten the log4net.dll with a new one and apparantly that's a big no-no.
All was well after returning the original (v.4.11.1) log4net.dll.
thanks for the feedback Corey!
is working on a reply...
