@bennygiardina The commands didn't work or they did work and RSS feeds don't work in that test profile?
If the former, see all the ideas on this page to see if you can get one to work.
Or, while Opera is fully closed, you can rename "/Users/yourusername/Library/Application Support/com.operasoftware.Opera/". Then, when done testing, you can delete the new com.operasoftware.Opera" and rename the old one back.
