[Req.] for defaultOK to return if packet loss = 0%

edit

I was hoping the defaultOK would return if the pings returned successfully to let us know if the device was there. It appears this script simply returns the defaultOK if the ping script was run successfully. Please correct me if I'm wrong.

Question

Pingbox does not function on mediawiki 1.14. It puts the below error over every page: 

Warning: Cannot modify header information - headers already 
sent by (output started at /var/www/wiki/extensions/pingbox.php:122) 
in /var/www/wiki/includes/WebResponse.php on line 16


Question

Product Version MediaWiki 1.13.2 PHP 5.1.6 (apache2handler) MySQL 5.0.22

Hi all,

Made some improvements to Pingbox and figured I'd post for the common good.

First, add this CSS to the appropriate file. I added it to the end of the main.css file for the skin in use: 

/* Tooltips with CSS  */
/* 2010-09-30: David Feinzeig */
/* Thanks to http://psacake.com/web/jl.asp */
a.tooltip{
    position:relative; /*this is the key*/
    z-index:24; background-color:#ccc;
    color:#000;
    text-decoration:none}
a.tooltip:hover{z-index:25; background-color:#ff0}
a.tooltip span{display: none}
a.tooltip:hover span{ /*the span will display just on :hover state*/
    display:block;
    position:absolute;
    top:2em; left:2em; width:35em;
    border:1px solid #0cf;
    background-color:#cff; color:#000;
    text-align: center}

Second, install this pingbox.php as per the original installation instructions:

Error (mw1.16.5)

edit

I'm getting the following error om MW1.16.5:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 132987824 bytes) in D:\xampp\htdocs\w\extensions\Pingbox.php on line 98

Here's my pingbox-statement: 

<pingbox>
host=http://www.google.com
defaultok=ok
defaultko=ko
labelinfo=
</pingbox>

Any ideas?
