Hi, I decided to try out CommentBox (Free Version) on my Joomla 6.x website, but it is not appearing when using Gantry5 framework. Out of the box, it works just fine in the default Cassiopeia template , mentioning "Login to Comment", when using the default permission settings [inherited] and the comment form nicely appears when the permissions "create comments" and "edit comments" are set to [allowed]. However, CommentBox DOES NOT APPEAR in the Gantry5 framework. How can I, being a non-coder, bypass/correct his problem ? Thanks in advance.

Hi Roland,
Thank you for trying CommentBox and for the detailed explanation — this helps a lot.
What you’re experiencing is expected behavior with Gantry5 and not a configuration issue on your site.
Why this happens
Gantry5 does not render pages using Joomla’s standard component output. Instead, it uses its own layout system. CommentBox currently relies on Joomla’s core rendering events to automatically inject the comment markup. Because Gantry bypasses those events, CommentBox is not automatically displayed — even though it works perfectly in Cassiopeia.
Good news: no coding is required
You can make CommentBox appear in Gantry by adding a small HTML block using Gantry’s built-in tools.
How to fix it (recommended approach)
- Go to Gantry → Layout Manager
- Open the layout where you want comments to appear (e.g. Article layout)
- Add a Custom HTML Particle
- Copy & paste the contents of the following Gist into it: https://gist.github.com/kavadas/0404d904ff4fd8800e696f8a72b9b40f
- Save and clear cache
That’s all — CommentBox will now load normally, including:
- Login prompts
- Permission checks
- Comment form
- Existing comments
Important notes
- This is a Gantry limitation, not a CommentBox bug
- The Free version works fine once the markup exists
- No PHP or JavaScript editing is required
- You only need to add this once per layout
Looking ahead
I am exploring cleaner integrations for Gantry-based templates (for example, a dedicated particle), but due to how Gantry works, automatic injection is technically not possible.
If you need help placing the particle in the correct layout or want screenshots, feel free to ask — I’ll be happy to help.
Best regards,
Lefteris

TYVM (Thank You Very Much) for your prompt reaction & solution
Working it in was even more simple & easy to implement:
In my template style I opened my Layout [Outline] and I simply added a particle called [Custom HTML], where I pasted the HTML code while leaving "process twig" & "process shortcodes" UNchecked.
I placed the Custom HTML particle in the "Mainbody" container, right under the [Page Content] particle.
Done
In my 25 year experience as a Joomla power user, this is by far the finest functionality & user friendly comment system I'm keen to recommend both, the tool and your service.
Thank you for that.
