Ciao Luca,

Have you ever read that? // L'hai mai letto? >> https://www.joomshaper.com/documentation/sp-page-builder/technical-requirements#support-limits

1. No support Joomla 3.x anymore. You had at least 2 years to upgrade CMS.
2. Joomla 3.x don't fully support PHP 8.4 (!), probably you Error Log is full with error messages ;p
3. SPPB 5.7.x (new) cannot work inside Joomla 3.10.x
4. If you have keep J3.x somehow, please uninstall current and install older SPPB 3.8.10.

BTW

• There is a new version of icagenda component that works with Joomla 4, and Joomla 5. I also use it on my projects.
• Helix3 is also a old template, consider using Helix Ultimate instead of it.
• Your site has also a few Web Accessibility issues, and becuse it's for EU market, you should correct it. A new EU law regulations are from 25 June 2025.

Thank you Paul, I could try to redo the site with Joomla 5.x but the problem is migrating all the content from SpPage because I can't export the created pages. And then there’s also the content from Icagenda. I'm not very experienced, but if you have any ideas about it, I can give it a try.

I don't know if it's possible to export the specific tables by making a dump and then import them into the new database.

Yes, possible to export-import component database tables, but it's not task for beginner. And as you probably know, it's beyond JoomShaper support.

I was thinking, if I install a previous version compatble joomla 3.10.12 of SpPage Builder could I solve the problem? Is it possible to have a download link?

Thank you

Yes, but remember to some plugins from SPPB 5.7 may stay and cause issues.

Yes, check download page, scroll down at the bottom and you will find 3.8.10 >> https://www.joomshaper.com/downloads/extension

Ok, I'll try tomorrow, thanks for now. I will let you know how it went. Good work.
