Hi,
Well this is pretty embarrassing. I really didn’t want to have to do a fresh install of WordPress and after some searching I realized that in the Discussion tab of the WordPress settings the option “Automatically close comments on articles older than X days” was checked. Cannot believe I overlooked that. My apologies.
Thank you so much for the answers to my additional questions. The edits are working perfectly!
One last question: is it possible to have a Sticky Sidebar effect for the right sidebar in a single post? I was looking into using the Theia Sticky Sidebar plugin but if there’s already an internal way to do it I would prefer that.
