Extension talk:Pingbox

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
Can someone tell my if this works for the folowing?

Product 	Version MediaWiki 	1.13.2 PHP 	5.1.6 (apache2handler) MySQL 	5.0.22

Improved version of Pingbox -- better formatting, MUCH better tooltips using CSS, etc.
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:

Second, install this pingbox.php as per the original installation instructions:
 * Hi Dave, i just replace my name by our name. --Boly38 15:08, 25 February 2011 (UTC)

Error (mw1.16.5)
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:

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

Any ideas?
