 * Hello,
 * I have an error in my admin panel :
 * Uncaught TypeError: b(…).not(…).filter(…).mediaelementplayer is not a function
   
   at HTMLDocument.a (load-scripts.php:463) at j (jquery-latest.min.js:2) at Object.
   fireWith [as resolveWith] (jquery-latest.min.js:2) at Function.ready (jquery-
   latest.min.js:2) at HTMLDocument.J (jquery-latest.min.js:2)
 * “add media” buttons doesn’t work with this… I’ve disabled my plugin, my theme,
   replace all the folders (wp-admin, wp-include, etc…).
 * An idea ?
 * Thank’s

 * When you replaced all folders, did you make sure that you deleted the old copies
   of files & folders before uploading the new ones?
