JMenuItem

Error bug: 0 Cannot access protected property Joomla\CMS\Menu\MenuItem::$params

https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4#JMenuItem

You can no longer retrieve the params property from JMenuItem directly. Use the getParams() method instead (available since Joomla 3.7)
JMenuItem::set and JMenuItem::get have been removed. Properties must be explicitly named
There is now a AdministratorMenuItem class which extends from MenuItem that contains extra public properties used for the Administrator menu item.

Hello ssnobben

What fix are you talking about on Helix? Unfortunately, PHP 8 support will be delayed for SP Page Builder 4. You have to wait until we release the stable version.

Best regards

SP Page Builder 4 supports PHP 8.0 now.
