I installed Rollup 11 on our development servers and after server restart CRM instance was broken. Every page that has grid or grids shown following:
I googled and found following solution:
1. Open regedit.
2. Open HKLM\SOFTWARE'\Microsoft\MSCRM.
3. Open TurnOffFetchThrottling key and change value to 0.
4. Make iisreset.
Once steps were done CRM instance was fixed.
