Hello Luo,
ok, in the meantime I tried the following:
I did the php debugging in WP as described in your link.
It worked.
With the
ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
in the wp-config.php the website crashed and on the frontend several errors displayed.
Disabling the plugins one by one I found the culprit: Toolset Types.
Only with Toolset Types enabled the errors occured.
In the backend errors showed that it must have something to do with an oxygen builder component called oxygen-toolset.php. Maybe or maybe not.
The error_log.txt displays the following errors:

With the code:
ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
in the wp-config.php the production website is crashed and I had to delete this code again to make the website work. But in the "background" these errors still exist. And I have no idea how to fix them.
Do you have some idea?
Greetings. Kai Peter
