Frequently Asked Questions
Common questions about SlimPress – Disable Unused Features, Heartbeat & XML-RPC
No. Every feature is off by default and activation writes nothing.
WordPress returns to its default behaviour on the very next request. SlimPress applies its changes through runtime filters and actions, so there are no core settings to restore. Deleted data does not come back: this includes revisions removed by the "Delete old revisions" button (which asks first) or by a revision limit when a post was saved, trash emptied under a shorter retention period, and WooCommerce scheduled actions and logs deleted under shorter retention limits. Image copies omitted during uploads while a Media switch was on are not recreated.
Every toggle that can cause a visible problem is marked Careful and explains what might stop working. The ones most likely to cause problems are: Disable the REST API for logged-out visitors - contact forms, booking plugins and WooCommerce blocks often use it. Add their namespaces to the allowlist. Disable WP-Cron on page load - scheduled posts, backups and automatic updates stop until a real server cron job runs wp-cron.php. Set that up first. Disable XML-RPC - the WordPress mobile app, Jetpack and pingbacks use it. Disable comments site-wide - WooCommerce product reviews are comments too. Disable global styles - block themes rely on these styles for spacing, colours and typography. Disable installing and updating from the dashboard - also stops security updates. Use this only on sites that are updated another way. Disable recovery mode emails - these emails help you regain access after a fatal error. SlimPress also warns you when an active plugin is known to need something you are about to switch off.
The version string is what makes browsers fetch a fresh file after an update. Removing it offers no measurable benefit and can leave visitors with outdated CSS and JavaScript. SlimPress also has no switch for turning off lazy loading, automatic sizes attributes on lazy-loaded images or big-image scaling, because disabling these features makes sites slower. The Media tab explains big-image scaling on an info card instead.
No. It works on any site. On a WooCommerce store, it warns you about switches that affect features the shop relies on, and the WooCommerce store preset preserves those features. A WooCommerce tab with its own switches (admin nags, tracking, background jobs and more) appears automatically while WooCommerce
SlimPress does not cache, minify or combine anything, so it does not overlap with a caching plugin. The performance test asks for uncached pages, and if a page cache responds anyway, it says so rather than showing you the cache's numbers.
Only if you click the optional PageSpeed button on the performance test tab. See "External services" below.
Yes. The Tools tab exports your settings as a JSON file and imports them on another site. The tab also lets you reset every switch to off.
Open Tools -> Undo a change. SlimPress keeps the last 10 versions of its settings - every save, group pause, preset, import and reset - and restores the version you choose. To find the cause first, pause one group at a time from its tab.
