Reply To: Converting Buddypress 1.8 to Bootstrap
No don’t mix files/templates from bp-default into your child /buddypress/, theme conpat templates and older bp-default templates have different structures. The point about theme compatibility is that the templates are template parts not full templates in their own right and inject their content into the WP function the_content() if you examine one you will note it has no header or footer calls.
Not sure what your asking re that theme but it’s suggestive of copying work?? and as such I’ll make no comment, however why not simply use that theme as it’s already built on boostrap and create a child theme as you need.
