Ajax Error!!! parsererror

Hello,

Yes there is an issue in the theme's file but it should not display anyway as wp-config.php is set as below:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', false );
define( 'WP_DEBUG_LOG', true );

The root cause is that the plugin somehow change the error reporting setting.

Thanks for your support.
