BuddyPress 1.5 was a huge release that introduced tons of changes and improvements that make BuddyPress more intuitive and responsive than ever before. A few things have changed since the “old days” of installing BuddyPress, most notably that you have quite a few more options at setup. We’ll walk you through the process, which is really quite easy, though those who are new to BuddyPress may have questions.
Before you install BuddyPress, make sure your WordPress setup meets the minimum requirements:
Server Requirement: PHP 5.2.4 or better
Server Requirement: MySQL 5.0 or better
Server Requirement: Apache Module mod_rewrite enabled for Pretty Permalinks
