[Plugin: WP Super Cache] Supercache files not generated

Hi, I’m having a bit of a confusing problem with WP Super Cache: Supercache files are not being generated at all.

(Side note: I recently configured nginx to properly serve static Super Cache files, but that shouldn’t be relevant.)

Useful info:

• Without a primed cache (i.e., after deleting the cache), I get this:

• At the bottom of the page:

  <!-- Dynamic page generated in 0.343 seconds. -->
  <!-- Cached page generated by WP-Super-Cache on 2010-08-01 19:14:47 -->

• In headers, nothing related to WP-Cache or WP-Supercache.

• After the first request (presumably when the cache should be primed), I get this:

• At the bottom of the page:

  <!-- Dynamic page generated in 0.343 seconds. -->
  <!-- Cached page generated by WP-Super-Cache on 2010-08-01 19:14:47 -->
  <!-- Compression = gzip -->

• In headers: WP-Super-Cache: WP-Cache

Here’s my setup:

• nginx 0.8.46 (running as web:web)
• php-fpm with php 5.3.3 (running as web:web)
• WordPress 3.0.1
• WP Super Cache Config:

• WP Super Cache Status:

• ON
• Cache Rebuild.
• Mobile device support (merely to get rid of the notice)

• Super Cache Compression: Enabled

All directories are owned by web:web.

The “Cache Contents” reports that nothing is cached by either WP-Cache or WP-Super-Cache.

Other plugins:

• Akismet 2.3.0
• Audio Player 2.0.4.1
• FancyBox for WordPress 2.7.2

• FeedBurner FeedSmith 2.3.1
• Google Analytics for WordPress 4.0.6 (with ‘#’ instead of ‘?’ for tracking)
