If you have entered a Silverlight player to your website, but not so you can watch in Mozilla Firefox, the problem occurs due to an error code in the HTML code. To fix the problem, we must edit a line of this code to do it.
How to fix it?
To fix the problem do the following:
Open the page where we have inserted the player with a web page editor.
We look at the section of the code, and add a comma "," at the end of the string data in this line that we can see in all HTML code (it should be as shown here)
This problem can also occur in browsers based on Firefox as Flock, Iceweasel, etc., which may happen on Windows, Mac OS, or Linux (installed Moonlight). Flock 3 is based in Chrome so this will not happen, but yes in previous versions.
Hint: For improved responsiveness use Internet Explorer 4, Firefox or above. Ensure Javascript is enabled and choose 'Normal' from the Layout dropdown and hit 'Update'. You must Sign In to use this message board.
