Less Items in Category Pages
Sorry for my slow response on this item (if you ever need a quick reply, be sure to send an email to wiki support). Category pages are cached for non-logged in users. If you ever manually edit the page, the cache gets then refreshed (dynamic driven content, such as new pages being added to the category do not cause the cache to be refreshed). You can also add ?action=purge after a page url to purge the cache. Please let me know if this makes sense.
