Hi, are there Quickstarter for Joomla 5 around (JP-Ultimate)? I just tried to upgrade the Quickstart Joomla and it went totally wrong, backend was dead

Quickstart always includes Joomla. Now you have installed Joomla into a previous Joomla installation and that destroys the entire installation. Quickstart always includes Joomla and a complete new installation. You cannot use Quickstart to update the template. Restore your backup and install just the template.

I see - i want to set up a fresh site, is there a quickstart that comes with Joomla 5 is what i meant?

Yes, install Quickstart and all example data will then be available.
But you need a new Database.

Yes quickstart is included, but only Joomla 4. Install the Joomla 4 and update to J5.
