First of all, everything seems to be working OK, so this isn’t about user experience bug (I don’t think). However, I’m using a plugin firewall (All In One WordPress Security) and immediately after the latest JW Player update (i.e., to V1.4.3) AIOWPS started reporting lots of 404 errors associated with the JW plugin. The URL that is repeatedly “not found” is: /wp-content/plugins/jw-player-7-for-wp-premium/includes/custom-script.js?ver=b8dd0a9728619d3715c9df33da8a67ee Is there possibly a problem with the newest update?
