Hi Nabeel,
I actually did create a sidebar for that page but it is being overridden by the other sidebar, which itself was only set up for use on one page and is not the default sidebar. As I said, I’ve done the things that I know to do to try and fix this but those solutions aren’t working. It’s as if that sidebar has become the new default. If I add a new page, that is the sidebar that is defaulting. I have tried deleting that sidebar and replacing it with a duplicate one but then it doesn’t work at all on either page. In fact, the duplicate won’t show the correct items, even though they are set up correctly in the sidebar widget. That goes for any new sidebars and sidebar widgets that I’ve created. Something is definitely wrong here.
