Frequently Asked Questions

Common questions about Optimazz – Website Optimization and Speedup

Yes. Network-activate it, then switch page caching on for every site in Network Admin → Optimazz (super admins only). Each site gets its own cache and keeps its own settings and cache exclusions. You can also activate Optimazz on individual sites only; then only those sites are cached.

Yes. wp optimazz status shows the page cache and active modules, wp optimazz purge clears the cache (or only given pages), wp optimazz preload warms it with a progress bar (add --background to run it on the server in the background), wp optimazz settings list|get|set|reset|undo reads and changes any setting (for example wp optimazz settings set css.minify on), and wp optimazz safe-mode on|off switches Safe Mode. On multisite, wp optimazz network status|get|set|purge|preload manages caching for the whole network. Changes are applied exactly like a save in the admin screen. Run wp help optimazz for every option.

Optimazz will not overwrite another caching plugin's advanced-cache.php drop-in. To use Optimazz page caching, deactivate any other page-caching plugin first. The other (non-caching) modules work alongside most plugins.

Page caching needs WP_CACHE to be defined, which Optimazz adds to wp-config.php automatically. If wp-config.php is not writable, Optimazz shows a notice with the line to add manually.

Delay-until-interaction is the biggest speed win but can affect scripts that must run before interaction. Start with "Delay" on and "Delay all" off, then add any problematic script keywords to the exclusion list.

Only opaque PNGs are converted, the original is optionally backed up to uploads/optimazz-backup, and the conversion is rolled back if anything fails.

No. Optimazz does not track users, register accounts, or send any of your site's or visitors' data to Optimazz servers. See the "External services" section for the only optional third-party hints the plugin can add.

Those small inline fragments (the delay-JavaScript loader, critical/async CSS, the lazy-load helper and LCP preload hints) are the actual optimization output that Optimazz writes into your front-end HTML. They are the product of the plugin's work, not the plugin's own asset loading — a delay-until-interaction loader cannot be enqueued as an external file. The admin interface and all of the plugin's own assets are loaded normally through the WordPress enqueue functions.
