FAQ
Frequently Asked Questions
Do I need the free plugin too?
Yes. The Pro add-on extends the free SiteVitals Speed Optimizer plugin. Install the free version from WordPress.org first, then add the Pro plugin.
How do I receive my license key?
Immediately after purchase, you'll receive an email with your license key and a download link for the Pro plugin zip file.
Will this conflict with other caching plugins?
SiteVitals Speed Optimizer Pro focuses on frontend optimization (CSS, JS, images). It complements caching plugins like WP Super Cache or W3 Total Cache.
What happens when my license expires?
Pro features continue working for a 7-day grace period. After that, Pro features are disabled but the free plugin continues working normally. You won't lose any data.
Can I transfer my license to another site?
Single-site licenses are tied to one domain. Deactivate the license on one site before activating on another. Unlimited licenses work on any domain.
Is there a refund policy?
Yes, we offer a 30-day money-back guarantee. If you're not satisfied, contact us for a full refund.
