Title: [Plugin: WP Super Cache] Supercache files not generated Last modified: August 19, 2016 --- # [Plugin: WP Super Cache] Supercache files not generated * [deanpence](https://wordpress.org/support/users/deanpence/) * (@deanpence) * [15 years, 10 months ago](https://wordpress.org/support/topic/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: - ``` ``` - 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: - ``` ``` - 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 - fbLikeButton 0.4a - FeedBurner FeedSmith 2.3.1 - Google Analytics for WordPress 4.0.6 (with ‘#’ instead of ‘?’ for tracking) - Google XML Sitemaps 3.2.4 - ShareThis 3.2 * [http://wordpress.org/extend/plugins/wp-super-cache/](http://wordpress.org/extend/plugins/wp-super-cache/) Viewing 5 replies - 1 through 5 (of 5 total) * Thread Starter [deanpence](https://wordpress.org/support/users/deanpence/) * (@deanpence) * [15 years, 10 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-supercache-files-not-generated/#post-1609328) * Thanks in advance for any help, by the way. This plugin actually helps me to host my customers at probably half the cost, even without static files. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [15 years, 10 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-supercache-files-not-generated/#post-1609511) * There’s probably something up with your Nginx rules. Unfortunately I’ve only used Nginx once and have since gone back to Apache so can’t help you there. 🙁 * Thread Starter [deanpence](https://wordpress.org/support/users/deanpence/) * (@deanpence) * [15 years, 10 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-supercache-files-not-generated/#post-1609545) * It’s a pity that such a great web server has such poor documentation and unintuitive configuration syntax. * Thread Starter [deanpence](https://wordpress.org/support/users/deanpence/) * (@deanpence) * [15 years, 6 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-supercache-files-not-generated/#post-1609818) * I haven’t dug around in the source code yet, but does the plugin refuse to write out supercache files when it can’t verify mod_rewrite is in use? * The only times I can get WP Super Cache to write supercache files is by the cache tester and preloading. But I’m hesitant to use preloading if the supercache files will never get regenerated. * Thread Starter [deanpence](https://wordpress.org/support/users/deanpence/) * (@deanpence) * [15 years, 6 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-supercache-files-not-generated/#post-1609819) * I’ve found the answer to part of this, and it’s listed on the very beginning of your readme file: * > [B]ecause a user’s details are displayed in the comment form after they leave > a comment those requests are handled by the legacy caching engine. * I was expecting supercache files to be generated even when I was logged in (I had “Don’t cache pages for known users” unchecked), but the plugin does not generate them when it uses legacy caching (i.e., when certain cookies exist). I started using another browser to browse as an anonymous user, and whenever I browse to them, supercache files are generated as expected. * **There still seems to be a problem with preloading, however.** When I enable preloading and enable a small refresh interval (e.g., 5 minutes): 1. The refresh interval is never saved. (I have to edit wp-cache-config.php and edit $wp_cache_preload_interval manually.) 2. No pages ever get preloaded until an anonymous user browses to them. (I’ve checked my logs to make sure wp-cron.php is getting called, and it is.) * Thoughts?
