FastMe setup, activation, and optimization guide
Complete step-by-step docs for plugin installation, license activation, common issues, and support. Each section has its own URL hash so your team can share direct links.
Overview
FastMe improves WordPress site speed with caching, minification, image optimization, and script control. Typical onboarding flow: install plugin, enter license key, activate domain, and apply recommended optimizations.
FastMe plans are designed for Starter (1 site), Pro (3 sites), and Business (6 sites), while your dashboard keeps subscription status, registered domains, and renewal-related data in sync. For best real-world performance results, use FastMe with a stable cache strategy on hosting and CDN, then measure after cache warm-up.
Prerequisites
Before installation, make sure you have WordPress admin access, an active FastMe account with an assigned license key, and the latest plugin package from your dashboard. Your hosting environment should allow outbound HTTPS requests to FastMe APIs and should provide proper write permissions for cache-related directories. It is also important to keep PHP and WordPress versions within the compatibility range of the current plugin release.
If your host blocks REST requests or outbound HTTPS, activation and metrics sync can fail. In that case, ask host support to allow outgoing calls to your FastMe API domain.
WordPress installation
Go to WordPress Admin, open Plugins, choose Add New, and upload the `fastme.zip` package downloaded from your FastMe dashboard. After installation, activate the plugin and open FastMe settings to paste your license key. Once activated, start with safe defaults such as caching and basic CSS/JS minification, then purge all layers of cache and validate key pages like homepage, product pages, cart, checkout, and blog templates.
License activation
Plugin sends `license_key + domain` to backend validation endpoint. If license is active and slot is available, domain gets registered under your key.
Plan capacity follows your subscription tier: Starter allows 1 active domain, Pro allows 3, and Business allows 6. If the same domain is already tied to the same key, validation remains valid. When all slots are consumed, activation is blocked until you either deactivate an unused domain or upgrade to a higher plan.
| Scenario | Result |
|---|---|
| Valid key + free slot | Domain gets activated and stored under license |
| Valid key + existing same domain | Activation remains valid (idempotent) |
| Valid key + no remaining slots | Activation blocked, upgrade/deactivate required |
Frequently asked questions
Why does activation fail?
Usually due to invalid key, expired subscription, or activation limit reached.
Can I move license to another site?
Yes. Deactivate on old domain, then activate on new domain.
Will settings affect Core Web Vitals?
Yes, especially caching, minification, and deferred script configuration.
Do I need to reactivate after plugin update?
Usually no. Activation stays attached to the domain unless license is revoked or expired.
Why score changed after deployment?
New theme/plugin assets, unoptimized images, or third-party scripts often impact score.
Troubleshooting
Most issues are resolved by clearing plugin, CDN, and browser caches after configuration changes, then testing again in an incognito session. If layout breaks, temporarily disable minification and defer options, then re-enable settings one by one to find the conflicting option. Also confirm your WordPress cron and REST API are healthy, review server logs for permission or memory-related errors, and exclude dynamic pages such as admin, cart, and checkout from aggressive caching rules.
Support
If you need help, create a support ticket with domain, plugin version, and issue details.
