Page Cache – Status = not cached?

@CyberOto- Submit the bug report from the w3tc support tab: http://yoursite.com/wp-admin/admin.php?page=w3tc_support

I’ll check my resource usage as well. Only one of my sites is on a shared host and it’s just a goof-off/test site. The other 2 are multisite on VPS at liquidweb (which I highly recommend).

Monthly bandwidth on my little shared, low traffic site averages around 1.20 Gig per month. Don’t see any particular spike.

The multisite is usually 40-50 Gig, up to 66.78 for August. Not seeing any particular usage spike.

This is apparently not a new issue- was being discussed here a month ago.

A poster from that other thread writes:

I contacted my hosting provider (Rackspace Cloud Sites), and they show that the pages are indeed pulling from the cache files. However, they weren’t able to determine why the cache files are being recreated for every page view.

So who knows if cached pages are being served or not….

True dat.

Looks like I’m having the same problem… everything was set and configured 2 months ago, and I didn’t really check to make sure everything was still working after this latest upgrade.

I’ve now disabled all but minify and cdn (i.e. all caching) and I’m seeing a very noticeable performance increase (compared to what was working before upgrade).

Something isn’t right with 0.9.2.4…

This fixed it for me:

In .htaccess, I replaced…

    RewriteEngine On

    RewriteRule ^(.*\/)?w3tc_rewrite_test$ $1?w3tc_rewrite_test=1 [L]

</IfModule>
# END W3TC Page Cache core

with…

# END W3TC Page Cache core

I think this means that my cached pages aren’t being gzipped, but at least now they are actually being cached and not regenerated each time.

Uncommenting these two lines, I get the “status: not cached” problem again:

#RewriteCond %{HTTP:Accept-Encoding} gzip
    #RewriteRule .* - [E=W3TC_ENC:_gzip]
