Set up comments
What you need: Simply Static Pro
Comments work on your static site too, with most of the heavy lifting handled in the background.
Enable comments
Go to Simply Static > Forms and scroll to the Comments section. Turn on Use comments.
Choose a redirect page
Use Select a redirect page to send visitors to a page of your choice after they submit a comment.
This is good practice because of what happens behind the scenes: when a comment comes in, Simply Static regenerates the post so the new comment appears, and that can take a moment. Redirecting the visitor to a friendly page avoids leaving them looking at a page that hasn't updated yet.
What happens in the background
When someone submits a comment, Simply Static sends it to your WordPress site and adds it using WordPress's own wp_insert_comment() function. Depending on your comment settings, it's either published right away or held for moderation.
Once a comment is published, Simply Static automatically pushes the post again so the comment shows up on your static site. Unlike forms, comments don't use a JSON configuration file. They work with JavaScript and a meta tag on your static pages to find everything they need.
Protect comments from spam
Comments are covered by the same CAPTCHA protection as forms. Set up Cloudflare Turnstile or Google reCAPTCHA v3 under the Captcha section of Simply Static > Forms. See Protect forms with a captcha for the steps.
