    The WordPress Firewall 2 plugin prevents BPS from being able to save custom code to Custom Code text boxes and also prevents the htaccess File Editor from working.

    Recommendation:  Delete the WordPress Firewall 2 plugin.

    Reasons for Recommendation:
    The WordPress Firewall 2 plugin has not been updated in over 3 years.
    BPS already protects against the things that the WordPress Firewall 2 plugin is protecting against using .htaccess code/files instead of doing this at the php level.  .htaccess files/code is processed first before php code and is a much more effective firewall method.
    The WordPress Firewall 2 plugin does whitelist the wp-admin / WordPress Dashboard area by default, but there is a code mistake so that default whitelist rule is not working correctly.  If you would still like to keep using the WordPress Firewall 2 plugin then see the fix below.

    Fix the WordPress Firewall 2 plugin:  Keep using the WordPress Firewall 2 plugin and fix the code mistake so that the wp-admin / WordPress Dashboard area is whitelisted.  BPS / BPS Pro will be able to function normally after making this code correction below.

    Open and edit this file:  wordpress-firewall-2.php at code line 158 and add the Yellow highlighted code below.

    function WP_firewall_check_exclusions() {
    	$request_string = WP_firewall_check_whitelisted_variable();
    
    	if ( is_admin() ) {
    	return;
    	}
    
    	if($request_string == false) {
    		//nothing to do
    	} else {
    ...
    ...
    ...
