Basically we downloaded "Sitefinity_3_7_2136_standard_patch" last week and patched my development machine with the SP4 by just applying the patch directly to the project bit-by-bit and everything is fine, site works ok on my local machine.
However we have another development server where users are actually using the site, adding contents to the site having different roles etc. The issue is, we are not able to upgrade that machine to 3.7 SP4.
The Issue is after applying patch to that development server we are getting "Data is Null. This method or property cannot be called on Null values" error. Surprisingly the database on my machine is copied from development server couple of days before patching my machine.
Than we tried upgrading as Gabe Sumner's video suggests using 3.7 SP4 blank project but as soon as it connects to the database we are getting the same error and we think it is to do with database.
we check some tables and the scemaversion value in tables are 2096 where is in my local machine the value in same variables are 2136.
What is that we need to do to upgrade the database or site?
We will appreciate your quick response.
