i guess i have to replace “function_that_creates_activity_form” with the real function name. could you please give me a hint on where i can find this specific function name?
thanks for this suggestion. just tested it and got an internal server error (500).
wordpress says now it has a critical error.
i also rather would like to disable the activity form for users instead of just not showing it, since you can easily bypass display:none in the inspection tools.
