Frequently Asked Questions (FAQ)
What's the difference between Really Simple SSL Pro and the free version?
The free version provides basic HTTPS enforcement and mixed content fix. The Pro version additionally includes: HSTS preloading, security header management, vulnerability scanning, firewall, login protection, multisite support, and more advanced mixed content debugging tools. For commercial sites or users needing a comprehensive security solution, the Pro version offers more value.
What should I do if my site shows errors after installation?
First, check if your SSL certificate is valid. If the certificate is fine, try enabling “Debug Mode” in the plugin settings to view specific error logs. Common issues include: server not properly configured for SSL, CDN not synced, or theme/plugin hardcoding HTTP links. The Pro version provides more detailed diagnostic tools.
Does Really Simple SSL Pro affect SEO?
The positive impact outweighs the negative. Forcing HTTPS is one of Google's ranking signals, and the plugin uses 301 redirects to ensure SEO weight transfer from old HTTP links. The mixed content fix also prevents increased bounce rates due to security warnings. Performance impact is minimal and won't slow down page load speed.
What SSL certificate types does it support?
It supports all major SSL certificates, including: Let's Encrypt free certificates, paid commercial certificates (like DigiCert, Comodo), and cloud provider certificates (like Cloudflare SSL, AWS Certificate Manager). The plugin automatically detects valid certificates on your server without manual configuration.
How do I uninstall Really Simple SSL Pro?
Deactivate and delete the plugin from the WordPress admin plugins page. The plugin automatically cleans up all settings and database records upon uninstallation, leaving no residual files. However, note that after uninstallation, your site will revert to HTTP mode, requiring manual configuration of redirect rules.
What is the price of the Pro version?
The official pricing is $49 per year (single site license), with a package supporting up to 3 sites at $79/year. There is currently a 40% limited-time discount available through the official recommended channel.
Purchase Advice: Free Version or Pro Version?
For personal blogs or small showcase sites, the free version is usually sufficient. However, if you run a commercial site, e-commerce platform, or need to handle sensitive user data, the Pro version's firewall, vulnerability scanning, and login protection features can significantly enhance your security level. According to Reddit user experiences, many people upgrade to the Pro version after using the free version for a few months due to incomplete mixed content fixes or the need for HSTS functionality.
Conclusion: SSL Security, Starting with One Click
Really Simple SSL Pro has become the de facto standard in the WordPress SSL space thanks to its minimalist deployment process and powerful mixed content fix capabilities. Whether you're a beginner just starting a site or a seasoned pro managing multiple commercial sites, this plugin can save you a lot of time while enhancing your site's security and SEO performance.
