Details

### Summary
The http_error_log file stores the $_COOKIE and $_SERVER variables, which means sensitive information such as database passwords, cookie session data, and other details can be accessed or recovered through the Pimcore backend.
### Details
It’s better to remove both lines, as this information makes little sense in this context anyway.
