I've developed several web apps upon this wonderful CMS platform, and our customers are very satisfied with them.
Now I got a problem after upgrading to the new version 2.3.9.0 from an old 2.3.6.7 one according to your guidance doc step by step:
Step 1: backup the whole application including files and database
Step 2: deployed the 2.3.9.0 deployment files into proper folder
Step 3: made custom changes, merged the source code, then recompiled all the programs
Step 4: run setup process and everything seems OK
But after upgrading, I can not edit settings for content instance anymore. When click any Settings link, system crashed and gave me error messages as following. Can anyone help me?
By the way. I am using .NET Framework 3.5/4.0, Windows Server 2008R2 x64, MS SQL Server 2005
