FAQ
Frequently asked questions
Does 404 Slimmer slow down my site? +
Not at all. 404 Slimmer only hooks into WordPress when a 404 error actually occurs. On normal page loads, it adds zero overhead. The logging uses a single lightweight database insert.
Is it compatible with caching plugins? +
Yes. 404 Slimmer works alongside all major caching plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, etc.). Since 404 pages are typically not cached, the plugin captures them reliably.
Can I migrate redirects from another plugin? +
The Agency plan includes bulk import/export in CSV format, making it easy to migrate from Redirection, Yoast, or Rank Math redirects. Pro users can set up redirects manually from the dashboard.
What happens when my license expires? +
The plugin continues to work. You just won't receive updates or priority support until you renew. Your 404 logs and redirects remain intact.
Is there a refund policy? +
Yes, we offer a 14-day money-back guarantee on all paid plans. If you're not satisfied, contact us and we'll process a full refund.
