Can not add Questions

I've installed your vQuiz software on my Joomla 3.4.1 installation. I seem to be able to add quizzes, categories, view the dashboard and complete the preinstalled quizzes. However, when I attempt to add questions to the existing quiz or a new one I've created, it won't allow me to Save or Save and Close.

I'm running on an Apache install with mySQL 5.1.73 and PHP 5.4.38. I've attempted using Chrome and Firefox. Any ideas?

Hi,
The issue is corrected in the latest version. It's upgraded on your site as well. Please check it now. it's working fine there.
