403 Forbidden on media/library

Hi,

I installed version 3.2.1 on a webserver (I tried some different hosts) and followed the installation instructions. I am able to log in, connect screens and change all the properties. But when I try to add some media I get a 403 Forbidden Error in combination of following info in my console: “DataTables warning: table id=libraryItems - Ajax error.”

I already changed all folder and file permissions. I don’t have a clue, what to try next.

PLS HELP :slight_smile:
