I installed W3TC (I've used it on other sites without problem), but after I did so I got 404 errors on two of my pages. I deactivated the plugin, 404s remained. I uninstalled, 404s remained. I checked the .htaccess file to ensure everything related to W3TC was gone (it was), 404s remained. I reinstalled and flushed the cache, 404s remained. I tried updating the pages and purging them from the cache on the pages page, but still have the 404 errors.
I even followed the instructions on this page: http://trebleclick.blogspot.com/2010/09/fix-404-pages-w3-total-cache-in-wp.html
I just can't seem to get rid of this problem! Can anyone tell me what's happening?
