JetPack Breaks FV Player in newest update

Hello Lacey,

I tried to reproduce the issue, but I wasn’t able to – all the videos are still working even with JetPack installed. However JetPack is a complex plugin, so the issue might be depending on some JetPack module which you are using. Which modules do you have enabled wp-admin -> JetPack -> Settings?

You can also try downgrading FV Player to version 6.5.2 and see if that helps. It can be installed from this link: https://downloads.wordpress.org/plugin/fv-wordpress-flowplayer.6.5.2.zip You will have to first deactivate and delete the current FV Player plugin you are using. WordPress will warn you that you might loose settings and data, but it’s not the case with out plugin, no settings now videos will be lost. Or you can just replace the plugin files via FTP.

Thanks,
Martin

Hello Lacey,

I’m posting what we found in the Pro support here to make sure we help other users too:

The problem was with your theme UnidashVersion By CactusThemes which runs HTML filtering function (wp_kses) when showing articles. It’s a standard WordPress function which strips potentially malicious HTML markup from the posts. Normally it only runs when saving the posts, but your theme is running it even on the HTML code added by plugins – which is non-standard. So we improved FV Player to handle this scenario – the fixed version is on your website already and we will make that fix part of the next release as well.

Second issue was that some plugin breaks the way FV Player works. And it’s not JetPack, theme must be some other change which was done on the website, like some other plugin update. However enabling “Load FV Flowplayer JS everywhere” fixed the issues, so the videos in your lessons now play. The downside of that setting is that the CSS/JS files have to load one each page, but it’s more compatible. Your setup seems to be loading the post content in some strange way which prevents FV Player to load its scripts without use of that option unfortunately.

Thanks,
Martin
