Hi,
I have a SharePoint 2013 farm recently patched up to October 2014 CU. Before the upgrade, I had installed and configured SSRS 2012 SP 1 (RS in SharePoint integrated mode) to the farm and it was in SP1 + May 2014 CU. After patching, I notice the site collection feature "SQL Server Report Integration feature" stops working. On new site collection, even it said feature activated, the SQL Server Reporting content type is missing.
Anyone experienced this behavior after patching?
