I recently upgraded my WordPress and plugins after moving to a different host. At least 1 post gets published every day on the blog but when I use mod_rewrite caching many visitors only see a post from May 9 as the last post. That also is the day we moved. When I use PHP caching, and remove the rules in .htaccess, it works fine. I had switched to PHP caching before because an Apache module, mod_headers wasn't loaded (which is now). Then it only occured to Internet Explorer, but after the module was loaded and I tried mod_rewrite caching, it happened in all browsers. Though it only happens to the frontpage, and not every visitor has this issue.
Ofcourse I would like to use the fastest method for caching, so any idea on how to fix this?
