We are using SharePoint 2013 Enterprise with SQL Server 2012. We have recently applied patches to SharePoint and SQL Server (SQL Service Pack 3).
I'm not entirely sure if the updates broke SharePoint reporting as we have now discovered that the reports in SharePoint no longer work, the following error is displayed in SharePoint:
An internal error occurred on the report server. See the error log for more details. ---> Microsoft.ReportingServices.Diagnostics.Utilities.InternalCatalogException: An internal error occurred on the report server. See the error log for more details. ---> System.IO.FileLoadException: Could not load file or assembly 'Microsoft.ReportingServices.ProcessingObjectModel, Version=126.96.36.199, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. Access is denied.
I've not familiar with reporting services and would be grateful for assistance
