I have upgraded to Joomla 4 I deleted all extensions that failed and then upgraded yet when I look at my home page I get this:
Call to undefined method Joomla\CMS\Application\SiteApplication::isAdmin()
and when I attempt to open an SP Pagebuilder page Home:
0
Cannot access protected property Joomla\CMS\Menu\MenuItem::$params
If I try and create a new SP page I get this: Error Field 'view_id' doesn't have a default value
