Before You Install

Before activating FastMe on a live website, create a full backup so the site can be restored if needed. When possible, test FastMe on a staging environment before enabling it on a production website.

If the website uses a CDN, server cache, builder cache, or another optimization plugin, clear all caches after making FastMe changes. Avoid enabling every aggressive optimization setting at the same time, especially on business-critical websites where stability is important.

Public PageSpeed tools only work on websites that are publicly reachable on the internet. Localhost environments, .local domains, .test domains, and many private staging URLs cannot be tested properly with external performance testing services.

Keep your FastMe license key private and secure at all times. Do not share it in screenshots, public repositories, support chats, or any publicly accessible location.

FastMe can work well with many WordPress themes and plugins, but compatibility always depends on the specific website stack. If an optimization feature causes layout problems or functionality issues, disable that feature first, confirm the site becomes stable again, and then continue testing more carefully.
