Reply To: Buddypress does not work right anymore
To follow up on @shanebp’s advice: It sounds like you’re experiencing problems with AJAX requests. AJAX requests are sent to wp-admin/admin-ajax.php, so your IP-based whitelist must exclude this URL. If your whitelist is built in PHP, something along the lines of the advice above will work. If it’s built in Apache or at the webserver level, be sure to exclude wp-admin/admin-ajax.php.
