Hi Ralf,
Thanks for reaching out.
There might be a few different reasons for this issue, I would suggest you troubleshoot with a few of the common issues:
- Theme Related Issue
- Testing Plugin Conflict
- Increasing PHP Memory Limit
If the above troubleshooting does not help and the issue remains, please add the following code to your wp-config.php for debug setup.
Please add the below-given code into your wp-config.php for debug setup, and the error logged into the file name debug.log inside the wp-content folder.
You can let us know if you find any error that is related to our theme or theme bundled plugins. We can do further investigation based on that.
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
//SET PHP INI DISPLAY ERROR FALSE
@ini_set( 'display_errors', 0 );
Please find the video will help you to edit wp-config.php and add the above code: https://www.youtube.com/watch?v=3SDPTafEM8o
