BuddyPress.org

hi @nickfisher,

It worked well for the first few weeks of use but since this morning it hasn’t been.

That’s because the breakfast coffee was too cold. 😉 What have you done before “this morning” ?

I suggest to review your install, as at the moment, nore the Members or the Groups button are working.
Their URL is correct: http://community.yourfreedomtrain.com/groups/, but loose the directory on click. Do you use a redirection plugin or script ?

Deactivate all plugins (jetpack,etc) while testing BP/WP. The couple should work properly before adding other tools.

You’re using a subdomain for BP. This can, so far i remember, only be done if WorPress is multisite configured. Is that the case ?
If yes, have you followed those install instruction ?

Has the htaccess file the correct requests for such a configuration ?

Otherwhise, prefer a standard install and use a directory for BP instead.
yourfreedomtrain.com/community/

Check that all of your active BP components have their own page.
