Re: Will activating buddypress wipe out my WP theme
There are a couple ways to make themes for BuddyPress.
One way is to make a child theme for bp-default. Instructions can be found here: https://codex.buddypress.org/how-to-guides/building-a-buddypress-child-theme/ This is a good option because it’s relatively simple, but it will restrict you to some extent to the general structure of the bp-default theme.
Another way is to integrate BP features into your own Svelt theme. The BuddyPress Template Pack will help you do that. https://wordpress.org/extend/plugins/bp-template-pack/ Basically, it provides the extra templates necessary (on top of your existing WP templates) to run BuddyPress functionality. Follow the Template Pack instructions carefully on a test installation, and see what you think. Once you’ve gone through the Template Pack setup, you can start customizing the way that BP integrates with your theme to your liking – but BPTP will give you a nice headstart.
