Permissions issue + icon upload issue

It is a stupid question but i can’t edit permissions in my client?
I searched on internet and saw pictures of a complete different permissions screen. Can anyone help me?
This is how i see it btw:

Edit:
I also got this error when i try to upload a icon:

I searched and found some others with this problem, but in most cases it was a firewall issue. But i host it on a VPS so i don’t know how to fix.
