Hi @bentomen,
In most cases, the default set-up after clicking Activate SSL is sufficient for your site to load correctly over HTTPS.
But always recommend a quick test of your site using the SSL Labs tool (https://www.ssllabs.com/ssltest/), which will help you confirm that the site is working correctly over HTTPS/SSL. If this test shows at least an A grade for your SSL configuration, you’re good to go.
You can enable the plugin’s other features by navigating to Security -> Settings and selecting the desired options here. This includes various other security features like Vulnerability Scanning and Email 2FA.
Kind regards, Jarno
