I have just upgraded Opmanager from 7100 by running the 7200 service pack without any problems and tested OK. I then stopped the services and ran the 7205 hot fix and rebooted the server. After it came up I logged in to Opmanager and got a blank screen with "ERROR!" in the top left corner and the rest of the screen blank.
After some searching on your forums I then stopped services and checked that the java, apache, and mysql processes were not running. I then ran a repairdb.bat file. It picked up a number of inconsistencies which it seemed to repair. I then started services and connected and got the same error again.
At this stage I am restoring the server using a Live State Recovery image taken before the service pack upgrade. Do you have any ideas on what could be causing the issue?
