Sorry, I had to downgrade to 5.3.8 because the websit was live. Here some info:

• joomla 4.4.8
• php 8.1
• I paste in hidden content the export of the page that got the error

Please take a full site backup with Akeeba Backup in ZIP format and share here. Follow this tutorial. I will check it on my localhost. I will update SP Page Builder version and check the issue. Until I fix, you can continue using SP Page Builder 5.3.8 on your live site.

Backup link in hidden content, let me know when you downloaded it so I can delete it, please.

You have provided the backup in JPA format. Please change the backup file type to ZIP and take the backup again. Then share the ZIP file.

no man, I shared you the .zip, download it and extract it

try this new one

I have installed the backup but could not get into your admin URL. What is your admin URL? Is it site/administrator or is there any postfix word?

in hidde Content the url

Please share your database access. I will solve it directly on your site.
