This is the code from line 35:
public static function cleanLine($value)
{
return trim(preg_replace('/(%0A|%0D|\n+|\r+)/i', '', $value)); <-----LINE 35
}

Hi mat_rapit,

I'm not sure what generates this warning - it's an empty string in $value but the clean function is called many times with different $values. You can usually hide PHP warnings by setting Error Reporting to System Default or None in the Site Global Configuration.

im fill up the 'reply to' field and the warning gone.
'Error reporting are still at 'default'
