HTTPS protocol enforced: plugin doesn’t work any longer

Hi and goodday,

Upon upgrading WordPress and I believe also FV Player, I stumbled upon an interesting issue.

The player won’t work anylonger because the HTTPS protocol is used in the header. To give you an example:

<link rel=”stylesheet” href=”https://www.zelfslank.nl/wp-content/plugins/fv-wordpress-flowplayer/css/flowplayer.css&#8221; type=”text/css” media=”screen” />

<script type=”text/javascript” src=”https://www.zelfslank.nl/wp-content/plugins/fv-wordpress-flowplayer/flowplayer/flowplayer.min.js”></script&gt;
<script type=”text/javascript” src=”https://www.zelfslank.nl/wp-content/plugins/fv-wordpress-flowplayer/js/checkvideo.js”></script&gt;

The browser can’t find these files, but can find them under http://

Now all my videos aren’t working because of this, and I couldn’t find a way to return to http:// in some setting.

Do you know what is causing this?
I have searched your forum but couldn’t find a solution.

Thanks for your otherwise great plugin!
Alex
