Hi,
please if anyone know about free theme that is compatible with any version of buddypress, buddypress activity plus and what wordpress version is the best. Last theme that I tried was Buddypress Corporate but the comments doesn’t work.

You can make a WP theme compatible with BuddyPress by installing and activating the BP Template Pack plugin and going through the compatibility process.

e.g. BP Template Pack walkthrough: Twenty Ten theme – https://codex.buddypress.org/theme-development/theme-dev-bp-template-pack-walkthrough-twenty-ten-bp-1-5/
