I´ve made some screenshots showing the problem. Even tried installing from scratch, no luck.
Since I can only post one image per message, plus I cannot post more than three replies, I can only show you the screenshot below.
I can provide screeenshots of config.json or system console showing that I have configured MaxUsersperteam or MaxUsersperChannel accordingly.
So my question is : Is this a limitation of the free version ? If so, we would need to move on to evaluate another tool since we definetly need more than 20 users on channels and teams.
If not (and I can see no such limitation in any documentation), please be so kind to point me in the right direction - what am I doing wrong ?
