The fix is confirmed as working so please check your website’s Root and wp-admin files under the B-Core >>> htaccess File Editor page >>> Your Current Root htaccess File tab and Your Current wp-admin htaccess File tab and see if the security filters were successfully automatically modified during the BPS Pro 5.3.3 upgrade. If the filters were not automatically updated then please manually change them in your website’s root and wp-admin .htaccess files. Thank you.
