@atjuch, do you have a plugin installed on your site which automatically adds JavaScript “onclick” event to a link? I see the following onclick function in the link and it doesn’t come from video lightbox:
onclick="javascript:window.open('https://vimeo.com/78994002?width=800&height=450');
Here is the full HTML:
<a rel="wp-video-lightbox" href="https://vimeo.com/78994002?width=800&height=450" title="" onclick="javascript:window.open('https://vimeo.com/78994002?width=800&height=450'); return false;">
<div class="wpvl_auto_thumb_box"><img src="https://b.vimeocdn.com/ts/454/911/454911893_200.jpg" class="video_lightbox_auto_anchor_image" alt="">
<div class="wpvl_auto_thumb_play"><img src="https://shortsinsurance.com/wp-content/plugins/wp-video-lightbox/images/play.png" class="wpvl_playbutton"></div>
</div>
</a>
