Hi, This is my development site: http://adspottestone.cf/all-ads/ As you can see there are three main categories. What I want to do is add a banner to header in Single Post in a certain category. For eg: one ad for single post in vehicles category another ad for single post in Property category I couldn't figure out how to do that using your plugin. So I googled and found these: https://wordpress.org/support/topic...ngs-to-specific-category-on-single-post-basis http://wpthememakeover.com/2014/04/...r-only-on-posts-from-a-category-in-wordpress/ But I couldn't make it work: Basically what I want is to show this ad: http://adspottestone.cf/wp-content/uploads/2015/09/Vehicles-Single-Ad-Page.jpg in this single page and all single pages in Vehicles category. http://adspottestone.cf/vehicles/toyota-allion-g-260-2013/ I assume single.php is the page I should be editing here. So herewith Im pasting its content too: http://pastebin.com/8yxCgYTz Please help me figure this out. Thanks
