Flash player error message pop up while watching Udemy course ?

  • I was suffering the same until i made these following steps :
    1 - Open Udemy course on private tab, if the video is working properly that means one of your extensions are blocking some scripts on website.
    2 - ⌘+SHIFT⇧+E (Mac) CTRL + SHIFT⇧ + E (Windows) : Browser Extensions window will appear, now disable one by one while refreshing the video page each time, you'll find surely the incompatible one.
    3 - Uninstall it and you're done.
    Note : This method was 100% Problem solver for me, if this wasn't the case with you i apologize for wasting your time.
