Of course this also might not have anything to do with the Plugin Firewall either. I think at this point you need to do the standard BPS Pro troubleshooting steps here: http://forum.ait-pro.com/forums/topic/read-me-first-pro/#bps-pro-general-troubleshooting and then let me know exactly which BPS Pro security feature is blocking which thing. At this point the assumption has been made that this is being blocked by the Plugin Firewall. Not sure if you already tested or confirmed that already by doing the BPS Pro troubleshooting steps, but things could require a plugin skip/bypass rule or something else. By doing the BPS Pro troubleshooting steps you can isolate which thing is causing what.
If you would like for me to do that then I need to know specifically what is not working. Ie a link to what is not working. The name of the plugin that is not working. And a specific description of what is not working.
