Hello,
I purchased the Community Quizzes component, which I need to use on a site that runs on Joomla 2.5, so I downloaded the 3.5.4 version which should work fine for my Joomla version.
However, after I create my quizzes, I get this error when I try to use them:
Error 500: JHTMLBehavior::tabstate not supported
Am I doing something wrong? Which version of the component am I supposed to use on my Joomla site?
Thanks in advance
