When the page is displayed with IE8, it has following warning messages. The question is where these errors are checked:
The line 1 and 2 is blank in the view source, how come it complains some characters in it? What does line, char and code in the message mean? Do I check the HTML from the php code or the line 1 of php code to find missing ")"?
