If admin activity does not work at all validate the cvar again in console or in game with amx_cvar amx_show_activity please.
Amx_show_activity 2 broadcasts other things like slap and vote for instance.
To test language.
Change it to English. If it works then we need to work on the language file.
Make a clean install or plugins.ini without anything 3rd party and test the CVAR. It works. If not reinstall if you cannot find it unfortunately. Clean installs do not do this.
