Hi,
Open wp-content/plugins/contus-video-gallery/configXML.php file then find ob_clean(); and hide the code and check. If you are still facing the same issue, share your site link. So that I can check and assist you accordingly.
Hi Lionamol,
I have checked the link and noticed that the player and related videos are displaying fine. Please refer http://screencast.com/t/jJRjR2AQ. Clear your browser cache and check once again. Also noticed that you have disabled progress bar option in WP admin -> Video Gallery -> Settings page. Please enable that option.
Feel free to contact if you are still facing any difficulties.
