Issue with WebApps

Hello there,

The WebApps UI gets changed, also not able to open any link after login. Not sure the root cause for this issue. Nothing writes in the log file. I was working in this same environment last week without any issues. But something messed up after CU2 update i guess. I  have executed  WebApps2.01_App and WebApps2.01_Sys SQL files. Can anyone come across this issue?

Version : HF37641

SL version : SL 2015 CU2

Thanks,

Karthik
