Everything was working fine, but when I checked error_log file, I found many PHP error messages like:
PHP Warning: Use of undefined constant ‘DISALLOW_FILE_EDIT’ - assumed '‘DISALLOW_FILE_EDIT’' (this will throw an Error in a future version of PHP)
You can get similar error message for other WordPress constants on PHP 7.2 like:
PHP Warning: Use of undefined constant ‘DISABLE_WP_CRON’ - assumed '‘DISABLE_WP_CRON’' (this will throw an Error in a future version of PHP)

Example:
define( 'DISALLOW_FILE_EDIT', 'true' );
define( 'DISABLE_WP_CRON', 'true' );
