Frequently Asked Questions
Common questions about Flex Cache
No. Flex Cache stores full HTML pages. An object-cache plugin stores WordPress objects (options, queries). They can run together. Flex Cache will not install object-cache.php.
Only if Redis requires AUTH and you want early hits from Redis. The password in Flex Cache → Redis is stored in the database and is used after WordPress loads (writes and admin checks). Fast page serving cannot read that option yet. Add define( 'FLEX_CACHE_REDIS_AUTH', 'your-password' ); above “That’s all, stop editing!” if you need Redis on those early hits. Otherwise files are used.
The PHP Redis extension is missing, or no Redis server answered at the saved host and port. File cache still works. Save the connection after Redis is running; On stays disabled until the Server badge says Connected.
Possibly. Only one plugin can provide fast page serving. If another cache plugin already wrote advanced-cache.php, Flex Cache will not overwrite it. Disable that plugin first, then click Turn on fast page serving.
You are logged in as an administrator. Logged-in visits are skipped on purpose. Load a page in a private/incognito window, then refresh Settings.
Only if you click Enable WordPress cache mode. It inserts define( 'WP_CACHE', true ); and keeps a .flex-cache-bak backup. You can add the line yourself instead. Uninstall does not remove that line.
Fast page serving is turned off (only if Flex Cache turned it on), cached files are deleted, Flex Cache Redis keys are cleared if Redis was On, and settings are removed. WP_CACHE in wp-config.php is left in place.
