Log in screen breaks after Pega Platform upgrade
Hi,
I have just upgraded Pega Platform 7.4 in my local machine to Pega Platform 8.21 following upgrade manual. After upgrade, I am able to log in and things seem to be working fine, but log in screen breaks as below.

I have deleted entire files under temp directory including old Extract Marker file (PegaRULES_Extract_Marker.txt) to refresh the system, however this issue is not resolved. Why is this happening? Should I truncate cache tables? If so, cache tables varies per version but which ones exactly? Or if there is anything I should do after upgrade, please let me know.
Thanks,

Hi,
This might be css cache issue,
Did you try logging in incognito mode?
try deleting browser cache and the DB cache and log in.
Get back to us here, if it didn't help.
