Pimcore database imported but no Data Objects available

Support Installation
#1

I recently installed a copy of an existing Pimcore-environment on my local machine with XAMPP. I am able to log into the admin interface. The database and all class-definitions are imported.

The Data Objects panel is still empty. What am I missing so that I have them available here as well?

Kind regards Philipp

Have you checked the network inspector in the browser developer tools for errors?
