I have just had a customer point out that FAQMasterFlex does not work. If you look at the script vendors website http://www.lethalpenguin.net/design/FAQMasterFlex/ when you click on a FAQ topic you can see the FAQs associated with it, however in your demo and via our installation of softaculous this will not work.
Also once installed you cannot add or delete FAQs
I have tried this on other servers with softaculous installed and get the same result.
