FV Player Check Template display :

It appears there are stripping the query string versions as https://www.bijoux-lavault.com/wp-content/plugins/fv-wordpress-flowplayer/flowplayer/modules/flowplayer.min.js appears without the plugin version number.

Some site speed analysis tools recommend doing so, but it means you loose control over what version of plugin files is cached (in users’ browsers and on CDN). That way users hang on to the old plugin files and might experience visual or functional issues with FV Player (and any other plugin).

You can read all the details in our article: How to use WordPress with CDN.

We also recommend you to open any of your videos on your site and see if you get a red warning message about JavaScript not working.

jQuery library found: https://www.bijoux-lavault.com/wp-includes/js/jquery/jquery.min.js!

Martin,

I cleared the cache server and edge cache. Message remains the same
Can’t find your options in FV Player setting compatibility
