I have a page that is supposed to show a video. It works fine on my local server. No errors popup. But when it is live I get the following shell_exec error
````<source src="http://mysite.com/content/8-annual13/myvideos/19028.mp4" type="<br /><b>Warning</b>: shell_exec() has been disabled for security reasons in `````<b>/home/mysite/kirby/toolkit/lib/system.php</b> on line <b>73</b><br />"></source></video> I took a look at the kirby files referenced. But I'm still not sure how the mime type is not being recognized. Is this a problem on my server?
