@ John James Jacoby, the code you provided I put on bp-custom.php under /wp-content/plugins/ directory (not ‘wp-plugins’), and it seemed to work fine. However, when putting the code at wp-config.php, it doesn’t work.

Thanks for the suggestion, at least I don’t have to always edit the bp-core.php everytime I upgrade my buddypress installation.
