Hello, I'm totaly newbie in PHP and it is my first post so don't be to mean:D
Today i had similar problem.
Problem was in bad file path.
I'm using WAMP pack so probably this is diffrent situation, but if you are using PHP as Apache module, your PHP.INI have to be somewhere here: "/php5/apache/php.ini "
in XAMPP:"apache/bin/php.ini"
in WAMP: "wamp/bin/apache/Apache2.2.11/bin/php.ini"
In first moment i tried to edit: "wamp/bin/php/php5.2.8/php.ini".
That was my mistake. This .ini was first one I found. :'(
I have php 5.2.8
xdebug - php_xdebug-2.0.4-5.2.8.dll
everything is ok now.
