Last week I was able to see the roles and modules of existing users and for new users as well, but today I am not able to see for existing users or new users.
Reload (ctrl + shift + r) and check it.
If you system manager then you can see the role permission tab.
I tried hard refresh but, it didn’t worked.
It is fixed now.
It was some role permission related issue, I had removed delete and export permissions for almost every document which caused this issue, I revert everything back to normal and now I am able to see the user roles and permission.
