Pascal, thank you for response.
I have updated your plugin recently, but the problem still persists.
You can see it here if you open it in Chrome: https://sahaja-lib.info/?p=600. But if you open it in IE – it works. So the problem is not in url, but in player itself.
Thank you glmitchell! You helped me very much! Hour hint worked on Minimal Xpert theme.
