This is typical of Debian + Ubuntu + derivative systems.

Here's how to fix this on Ubuntu.

1) locate xdebug.ini | grep apache2

2) verify there's only a single /etc/php5/apache2/conf.d/*-xdebug.ini file

3) /etc/php5/apache2/conf.d/20-xdebug.ini is best one to keep, as this is
    conf file package manager effects during updates

4) remove others, like /etc/php5/apache2/conf.d/05-xdebug.ini

5) if problem persists, try - php -i | grep xdebug.ini - which will give
    you the cli conf file load order, then change out /cli/ for /apache2/
    in the resulting links

6) if all else fails, you may also find what you're looking for in phpinfo
