You appear to be using my invitations plugin. Could you open an issue on GitHub?

Hello
For some reason this option is missing from the settings, although it does come up in the settings search.
I can upload pictures to posts but no other file types.
Havent found the answer so asking here...
This became a global privilege so you can find it on that page. Seems like the language key wasn't removed from the settings page so it is still showing up in ACP search.
