Key Features
SSL Insecure Content Fixer starts with a Simple correction level that addresses common insecure content references. Administrators can select more comprehensive levels when a site needs additional processing. On multisite, network defaults can be applied while individual sites use their own settings where required. The plugin is designed to reduce mixed content warnings and provides guidance for diagnosing references that need separate attention.
Security Assurance
The certification review examined who can change correction settings, how the selected level is stored, and how resource references are processed in page output. HTTPS detection and multisite defaults were part of the scope. The evaluation considered input and output handling around these controls, including configuration that affects several sites in a network.
