This kind of error occurs because the browser of your Flash player was not capable of debugging. You can try to resolve this problem by downloading and re-installing the debugger, visit the adobe website to download the newest version.

If you are using Google Chrome as your browser, you should disable its linked Plug-in Adobe Flash player; normally it is the reason why the Flash Player Plug-in content debugger failed to work.

Start disabling it by launching your Google Chrome, then input “about:plugins” in the URL then click “Enter”

Look for the “Flash Plug-in” and try to broaden the division by selecting“+Details”

Disable “gcswf32.dll” once you are in the “expanded Flash division or section”.

The Google Chrome will now automatically run the plug-in Flash player content debugger.

 Another way to resolve this problem is by rechecking if your browser is supported with debugging.

Try to check it by going to “Window” then “Preferences” and select “General” then “Web Browser”

Most browsers that are supported with debugging are Internet Explorer and Mozilla Firefox.

There is possibility that you are using an anti-virus, such as NOD32, it act as a barrier in any communication done with the browser.

You can modify it by going to the page of NOD32, HTT/ Web Browsers, then once you’re there uncheck the small box with “Debug the Flash Application”
