Can't Open Rule-Obj-ListView record
I'm working on the PVS Pega v 7.1.9 downloaded from Academy link. I built an entire application and it was working fine until yesterday. Now I can't open any list of Instances.
I have run the index builder from SMA, and cleared all the logs and static contents from the server, however I'm still getting this error. Please help!
