Sidebar not displayed where I expect it to?
A common cause of the problem is that the sidebar conditions are invalid, meaning that they will never be met by any page on your site.
An example of unreachable an condition is “All Posts AND Search Results”. Instead, this should be changed to “All Posts OR Search Results”.

Another common issue is that your theme or another WordPress-plugin uses WP_Query in a way that makes WordPress – and thus Content Aware Sidebars – think that the content being viewed is something different. Deactivate all other plugins to see if the cause of the problem is there. If that does not work then click here to ask for support.
Also remember to set either (or both) the Singulars and Archives option for your conditions.
