(PC) Support tip - PC has encountered a fatal error Height must be non negative Parameter name:value

In PC12.53P4 when attempting to open a loadtest designer for a PC loadtest in ALM project website, it throws error: Performance Center has encountered a fatal error Height must be non negative Parameter name: value. Issue occurs independent of the projects and also problem is more evident from ALM website. When logging into the project through myPC, it does not show the error

Issue occurs  due to an integration issue between ALM client and the PC usersite interface on the PC Server. To resolve this issue, apply the fix from the below KB article on the PC Server. The zip file has instructions on how to apply the fix.

After applying the hotfix, make sure to:
i) Clear browser cache on the ALM client machine where website is accessed from and the error was displayed

ii) If there are more than 1 PCS in the setup, best way to test this is by keeping only 1 PCS active and making other PC Servers unavailable.
