Support » Plugin: W3 Total Cache » W3T Cache settings

  • Can anyone tell me why w3tc is not storing cache files in the wp-content/w3tc/pgcache folder? I do have Page Cache on, and I have Cache Preload set on. Could those files be in the wp-content/cache/page_enhanced folder instead?

    Also, I could use some advice on the Cache control settings. I have them set for “Cache-Control: max-age=3600, public, must-revalidate, proxy-revalidate” – is that the best setting? I’ve read up on it, but seen conflicting advice.

    One last thing – I have a dedicated server, so should the Page Cache be set on the ‘Opcode’ setting rather than ‘Disk enhanced’?

    Thanks for any help.

    Not storing cache files It’s typically a permissions issue, unless you’re not saving to disk. The cache control settings that work for you really vary based on your content. Most people set them according to google’s recommendations. Disk enhanced is best for most servers unless you’re aware of specific needs.

    Thanks, Frederick. Wouldn’t w3tc notify you if it couldn’t write to a folder, like it does when it can’t write to .htaccess?

    When you say Disk Enhanced is best for most, are you speaking of the Page Cache, or all of them? I currently have the Object and Database caches set for Opcode, since that’s under “Dedicated / Virtual Server” and I have a dedicated server. I read somewhere that that was how it should be, but I’m not sure. (Minify is handled by Cloudflare.)
