Reply To: unwanted pop and recent post tab

Hello,

If you mean the Recent posts in the sidebar, you need to remove the Recent post widget from the Main Sidebar area in Appearance > Widgets.

I have created a post and a page https://gyazo.com/4a50db19020f0207f4212d55f4dc3659 and https://gyazo.com/d5ee80dd896cadc5f5872224b381ab56 and see the posts in the sidebar onlhy.

Best Regards
