Just took a look at it, and since 'Classifieds' is a completely different section than 'Forums' (Forums, Members, Events, Classifieds), when you click on 'New Content', it only displays one section. I cant look at new content for 'Forums' and 'Classifieds' at the same time. Previous, the classified section was a sub-forum of Forums so all the topics were visible when clicking 'New Content'. Now that its its own section now, the content is separate from the forum info.
Also, clicking 'New Content' within the 'Classifieds' only shows one post although there are at least five new posts. No changes in ads displayed when you alter the 'By Time Period' selection.
Figured that should help narrow down your troubleshooting. Good luck and thanks again for all the updates :)
