Hi Marius,
Thank you for the details.
A 500 Internal Server Error is a generic server-side error, so we'll need to identify the exact request that's failing.
Could you please open your browser's Developer Tools (press F12) and go to the Network tab? Then try to save the page again and inspect the failed request.
Please share the following information from the failed request:
- The Request URL
- The Response tab content
- The Preview tab (if available)
- Any error messages shown in the Headers or Console tab
- A screenshot of the failed network request, if possible
This information will help us determine whether the issue is coming from the server, Joomla, SP Page Builder, or another extension.
We look forward to your update.
Best regards,
