I figured it out on my own. It was slightly different than what you suggested (for #1) – There were items in the ‘Displayed Everywhere’ section of Widgets that I made inactive, and this corrected the issue. All good, I’ll close out this ticket. Be well.
The YouTube worked, but it appears ABOVE my page name (see http://www.lifescaper.com ‘Home’ page to see what I mean) – How would I make it appear BELOW the page name?
As for the other question, I dragged a ‘Text’ widget into/under the ‘Sidebar One Page Portfolio’ section and left it blank. I still see the blog stuff under my links in the left sidebar. Did I do this incorrectly? My whole goal is to NOT have the left side scroll down with the right side, and I don’t want that blog stuff there anyway.
Thanks for your further help.
