BuddyPress.org

Hi @jannetto96-

I can verify that adding a buddypress.php or community.php file to the root of the active theme directory does result in BuddyPress using that file preferentially over something more generic. Please check that the new file has been created with permissions that allow the _www user (or whatever your webserver runs as) to read the file.

Next, try it with a different theme, like TwentyNineteen or similar. It could be your theme is loading templates in a nonstandard way.
