chromephp

I found ChromePhp to help with my PHP debugging woahs and installed the related Chrome plugin but I can't seem to get it to work. I originally put it in a folder in my redirected htdocs and added that to my PHP path in php.ini of xampp using: ; Windows: "\path1;\path2" include_path = ".;C:\xampp\php\PEAR;D:\htdocs\includes" That didn't seem to work I kept getting errors like the one below whenever I tried to include the file and output a ChromePhp::log("message") Warning: Cannot modify header information - headers already sent by (output started at D:\htdocs\ask.ca\wp-admin\menu-header.php:91)
