hi

1. is it possible that there's some file that has incorrect characters on the filename? (such as apostrophes...)

could you check that?

2. this looks like CSS...

3. I will take a look.

1. The player does not work only on this page. In other places, the file names do not matter. Side script also is not loaded on the artist page. I think the reason is different ...

have you checked ALL the albums (from QUEEN)? do they ALL work?

Yes.
Aina - player NOT work

1 album - works FINE

well there's some JS error on your website causing this. it's not music collection

I can see jwplayer is being loaded also by "allvideos" plugin. this could be the problem

also, there are errors of syntax on some javascript code, which si NOT generated by Music collection:

var desktopnotifications = 1var displayplayer = 1;

this particular piece of code is found there in that webpage, and it's a syntax error. this is NOT CAUSED by music collection

you must find the extension responsible for this error and solve it...

this is on line 103 of the source code of this page: https://rock-catalog.ru/a/1727-aina

just for your information...

Thank you, it really scripts conflict, in particular "allvideos plugin". I will think about how to solve it.

2. this looks like CSS...

There is some advice on what to pay attention?

FYI, there is an issue with the desktopnotifications code. Mine looks like this using the latest muscol...

  <script type="text/javascript">

var base = "https://www.domain.com";

var extrabase = "";

var desktopnotifications = 0

var displayplayer = 1;

jQuery(document).ready(function(){

	jQuery('.hasTooltip').tooltip({"html": true,"container": "body"});

});

  </script>

Note the lack of ; after 0. In any case, setting this to 1 or 0 makes no difference, notification prompt is still displayed to the user so I ended up hacking jwplayer_functions.php to remove the eventlistener.
