Hi,
I see the error.
This kind of 403 error while saving an SP Page Builder page is usually caused by server security rules, not the template or SP Page Builder itself.
From the message in network tab, it looks like your server (or hosting firewall) is blocking the request when you try to save. This commonly happens due to:
- ModSecurity rules on the server
- Firewall or hosting-level security filtering certain requests
- Restrictions on POST data (SP Page Builder sends large/complex data when saving)
Here are a few things you can try:
- Contact your hosting provider and ask them to check ModSecurity logs and whitelist the rule that is blocking the request.
- Temporarily disable ModSecurity (if your hosting allows it) and test saving again.
- Ask your host to ensure there are no restrictions on /administrator or large POST requests.
Since the frontend loads fine and the error appears only on save, this is almost certainly a server-side restriction, not an issue with our product.
Thanks
