Hello, I would buy this plugin, but after having tested the free version, here is the error obtained at the launch of my site:

Catchable fatal error: Argument 1 Passed to plugin \ Content \ MavikThumbnails \ ImgTag :: initParams () must be an instance of Joomla \ Registry \ Registry, instance of JRegistry Given, called Expired in / home / www / CHAMPAGNECUGNETJOOMLA3 / OKOK / plugins / content /mavikthumbnails/mavikthumbnails.php on line 159 and defined in /home/www/CHAMPAGNECUGNETJOOMLA3/OKOK/plugins/content/mavikthumbnails/imgtag.php on line 297


Could you help me ?

Thank you
