Page caching mechanism is somewhat very confusing. Which page to purge ? does the archive need to purge to? how about the widget? We know that W3 Total Cache already have mechanism to purge archive page with similiar tag / category (post term purge). However this is not sufficient. Consider this scenario : Web sitemap : Home /category/category_1 /post_type_2 /pages_x(contain post_type_2 with custom WP_Query ) With normal W3 Total cache if you publish post with post_type_2 and category 1 the /pages_x will not purge ! Our solution is to purge all the page cache during a post is marked publish. When all page is purged ? There is new post marked as publish (updated or new post) Post move to trash Setting Recomendation Do not prime/preload page cache , this will slow your site Use disqus/livefrye for your comment, it will reduce page cache problem Support Please use wordpress support forum here Or feel free to contact us at support@tonjoo.com and visit our site tonjoo Development Support Treat us a coffee!
