The click cannot start the video in the page/post but open the Video URL

Please check whether jQuery is loaded on your site.

Yes Jquery is loaded, but your plugin give an error.

It can be due cause a Jquery version mismatch or a conflict with other plugins?

Can you send me a link where I can see the error myself?

When you click you are directed to youtube and not to the video play.

I considered a few things but I don’t see how to solve the issue in your case. Please deactivate all other plugins, clear your browser’s cache and check if Lazy Load for Videos is still not working. If it is still not working, change the theme to ensure that the issue is not caused by the theme.

Thanks kevin, but I think it is easier to uninstall your plugin.
