Hey Community
The background is: Migrating and Upgrading SP2010 to SP2013. I did it, and alot of it works, as it should, though I have one issue.
I did deploy all the solutions to both the 14 and 15 hive, and activated all the propper features. Now, I have one web-part which breaks down. It is a Web-part that communicate with a SAP endpoint, to retrive some data and show dem. The Web-part work fine in the 2010 environment.
As soon as I enter the site where the Web-part is placed in, I am being redirected to the “Maintanence Web-part, error message”. If I delete the Web-part I can access the site with no errors. The code works fine @ 2010.
The error I am getting is “value cannot be null”.
Unexpected System.ArgumentNullException: Value cannot be null.

Ok, so the solution was, sure that the SAP connection in the web.config file is migrated over to the new config file of 2013. That step i missed. Now it works as it should.
