thanks a lot. GR.

I have the same problem, I'm currently playing around with different versions of wordpress and filebase to see if anything fixes it. Have you come across any solution to this?

Yeah it didn't work for the latest (4.9.4) or 4.5.2 but it works fine for version 4.3.1. Hope this helps!
