In the DotKernel version 1.6.0 , released on May 16th, 2012 we have removed the GPL'ed WURFL PHP library , as the code it was obsolete anyway and also the structure of the XML file was changed.
Instead , we implemented the Scientia Mobile's WURFL Cloud PHP library .
Instructions about how to signup for a free account , and how to setup your API key can be found here .
In the near future, we will create a template in Wurfl Cloud API control panel, at Scientia Mobile, ready to be used in DotKernel implementations.
Also, we got a special license, please read the file:
