# [Plugin: W3 Total Cache] – Some problems

 * (@blutarsky)
 * [15 years, 10 months ago](https://wordpress.org/support/topic/plugin-w3-total-cache-some-problems/)
 * I have been using W3TC for a while, but lately I had to disable it :-\
 * The first problem I have been facing was blog’s feeds stopped working (like if
   no new posts where being issued); Technorati stopped updating my blog, and my
   blog started loosing authority and ranking 🙁
    So while disabling feeds caching,
   I read about limiting feeds items issued by WP, and I tweaked blog’s feed URI
   adding the following:
 * `?max-results=60`
 * Using a feed reader I could ensure that feeds where working back again.
 * At that point I configured the CDN using the self-hosted/subdomain technique;
   it took quite a long time to scan the whole db looking for attachments, and the
   plugin couldn’t make it to import my media library, so I manually FTPed those
   missing files to the CDN.
 * I’ve left the plugin on for a few days; in the meanwhile I have redesigned to
   site to enable CSS Sprites thoroughly.
 * Before uploading the new site version, I did the following:
    1) uploaded new 
   stuff to the WP install 2) disabled the plugin (within W3TC main page, not in
   the plugin’s panel) to allow users to surf while updating the CDN 3) Updated 
   the CDN manually 4) Erased all the caches, although I could notice a lot of file
   where being left by W3TC in the CDN in w3tc/min folder 5) turned on W3TC again
 * After a couple hours I noticed the following problems:
    a) a test page I use,
   with third-parties scripts disabled (Adsense, Analyitics, etc) was being served
   to end users in place of the proper one! b) an included php module, being run
   with asynch/Ajax/Jquery technique in the sidebar (shows WordPress.com stats top
   posts) was empty.
 * After all I have disabled the plugin again, awaiting for some help.

 *     ```
