I’m not able to fix the root cause, only the symptom.
The root cause is that the site uploader is embedding the wrong code to instanciate the site player. @holster is the only person who can ultimately fix the cause by investigating and fixing the reason why the uploader is not working as it once did.
In the meantime, if you want fix the player to work on the individual instances of the files you have uploaded, this is what I did:
I simply edited the posts that weren’t displaying the player and compared the lines of code in those files with the lines of code in a file where the player was displaying properly. I then copied the needed code from the correctly working files and pasted it into the incorrectly displaying files after deleting the extraneous code. If you have the preview pane displayed as you reply, you’ll see the player appear when you get the code correct.
I would be happy to go around and individually fix each instance where the players is not working, but I fear that would actually be counter-productive to fixing the root cause… “The squeaky wheel gets the grease”.
