Hi!
Upgraded my development environment from 2.x to 3.x and everything works fine there, so I continued with copying my development site (files) and database to my production environment and suddenly Pages and Modules are not showing up (see screenshot).
After clicking around a bit, suddenly it worked and pages and modules appeared. But after logging out and in again, the issue had returned.
I tested with different browsers and cleared my cache and cookies, but that didn't help.
What could be causing this, what should I look for?
Thanks in advance,
Jasper
