Problem in Viewing Sites without Flash Player in El Capitan for Mac

[Guest]

Ever since I upgraded my iMac to El Capitan, I have numerous problems including this particular one of being prompted to install Flash Player whenever I visit some web sites. Without the Player the site cannot be viewed or some garbage display would appear. However, this problem still stays even after repeated installation of the software. Please help. Thank you

Hi,

What browser, including version, is this on?
