What version of Opera are you using?
I have Opera Next 20 on my Win 7 machine. It works.
Firefox and Opera use the same plug-in, so if it works in FF, it should in Opera. If it doesn't... it may be a plug-in conflict in Opera.
Opera 19.0 is the version, windows 7.
It shows Flash Player is not installed in Opera but I have installed it. How would I get rid of plug-in conflict?
As well as Youtube other websites that use Flash Player dont work.
This is what you should see under "plugins" in Opera:
Make sure Flash Player is listed and enabled.
It comes from the same place as the plug-in for Firefox, so one won't work if the other doesn't.
If that doesn't work, try a clean install. http://forums.adobe.com/message/4041846
Please check if you have any Opera update is pending, if yes then please install that update.
I dont, I re downloaded Opera but still the same issue.
I have checked and it is enabled. Thanks, but I have already tried uninstalling it previously.
