I am trying to identify and eliminate problems which cause occasional overlaods and crashes on our server
In our error logs I just spotted this line and wondered what it might be and if I need to do anthing!
Please excuse my newbie ignorance
PHP Notice: Undefined index: HTTP_REFERER in .../plugins/system/admintools/pro.php on line 1296
The line reffered to is
$referer = $_SERVER['HTTP_REFERER'];
?
thx
Andrew
