Elementor is not loading in test environment

Hello everyone, I have recently purchased a WordPress hosting at Strato. With the help of the Elementor plugin I wanted to build my site in the test environment first. Unfortunately, I found that the Elementor plugin does not load in the test environment. I get the error message “No editing possible?” and should activate the safe mode. However, enabling Safe Mode doesn’t help and neither do all the other troubleshooting steps from the Elementor Troubleshooting page. In production mode, Elementor works fine. Have you had similar experiences and do you have a solution?
