Selecting the “Hide Sidebars when this post displayed on Single Post
page” option expands the content to fill the page, but the sidebar is
still displayed below the content section, it is just displaced
downward. It does this when I have a Weaver Show Posts shortcode in the post
I’m not sure if this started with the recent WordPress 4.2.1 upgrade
but it is affecting a large number of posts on our UnderwoodCommunity.org site. I use posts as pages on the site to enable a
many-to-many relationship between facilities and uses. If the visitor
scrolls down the post it results in a very unprofessional look.
