This extension REQUIRES the Core Design Scriptegrator Plugin, but there is no trace of this dependance in the description!
Also, this plugin IS NOT INCLUDED IN THE DOWNLOAD and in order to achive the most updated version ( which works flawless with joomla 2-5 ) one needs to pay for a full membership on the developer site.
If one download the free version of the plug-in ( actually 2.5.x.2.2.1 ) and istall it on a Joomla 2.5.3 than it WILL RESULT IN FRONTEND BROKEN WITH WHITE PAGE only displayed.
In few words, this is a fraudolent behaviour oriented to scam.
Also there is a clearly fraud in the statement reported on developer site(*), near the Script Generator Plugin version 2.5.x.2.2.2. It stated that public version is released few weeks later than paid one, but IT HAS BEEN RELEASED on March 22th, 2012 and yet THERE IS NO FREE AVAILABLE DOWNLOAD.
This means that the developer intend to force users to obtain a PAID MEMBERSHIP IN ORDER TO RESTORE THEIR SITE functionality. ( In some countries this is considered forced extorsion! )
This statement is to be considered fraudolent since there is no warning in the download section for free users about Script Generator Plugin "known" problems and incompatibility!
