Frequently Asked Questions

Common questions about Auto-Install Free SSL – Generate & Install Free SSL Certificates

After generating an SSL certificate with this plugin, if SSL installation fails and you see such an error message: "Certificate verification failed! The system did not find the root certificate that corresponds to the supplied Certificate Authority Bundle’s intermediate certificate. Please supply a full Certificate Authority Bundle with the root certificate included." Previously, only the intermediate certificate was included in the CA bundle, which caused installation failures on hosting servers (including cPanel servers) where the root certificate was not present in the local trust store. Version 4.6.3 and later now always includes the root certificate in the CA bundle, which resolves this error. Please update the plugin to the latest version. This fix also ensures correct handling of Let's Encrypt's newer Generation Y chains, which can contain more than three certificates.

Sorry, it doesn't. Installing the plugin and installing SSL certificates are two different processes. After installing this plugin, you need to do some steps. Please check the 'AFTER ACTIVATION' section in the documentation.

Please check the 'Benefits of installing an SSL certificate on your WordPress website' above.

Please check the documentation. This documentation is for the free version of the plugin. If you want complete automation, please check the Premium version's video tutorial (1:42 min) at the top of this page.

Please click here to learn about installing an SSL certificate on your WordPress website. FYI, the Premium version installs SSL certificates with complete automation.

Please check the log. It is located in the plugin menu. Most probably, you see an error saying 'unable to register the account' along with the following text in the log: urn:ietf:params:acme:error:invalidEmail Let's Encrypt™ API throws this error if an invalid email was set as the admin email of your WordPress website, for example, "yourname@yourdomain.mamp" or "anything@example.com". Let's Encrypt™ expects we should register an account with a working email. To fix this, please update this plugin to the latest version and try generating the SSL again. Then you'll get a text field to update the admin email address. Feel free to contact us through the WordPress support forum if you still need help with any issues (with the complete log).

Please visit the plugin's 'Force HTTPS' page and click the 'Activate Force HTTPS' button.

This is a temporary issue. You may wait 24 hours or follow these steps: Please access your website with HTTPS (e.g., https://example.com). If you are sure that the SSL certificate is installed correctly and the padlock is visible, please log in to your WordPress dashboard, open a new tab, write the following URL in the address bar by replacing 'www.example.com' with your domain name, and hit enter: http://www.example.com/wp-admin/admin.php?page=aifs_force_https&aifsaction=aifs_force_https_override&checked_ssl_manually=done&valid_ssl_installed=yes

Please click the 'Revert to HTTP' button on the plugin's 'Force HTTPS' page. Alternatively, open the email you received after activating the HTTPS redirect (or Force HTTPS) and click the link to deactivate HTTPS redirect and revert to HTTP. The subject line of that email is "'Auto-Install Free SSL' has activated Force HTTPS on your website YourDomain.com". [Replace YourDomain.com with your WordPress website's domain].
