I\'ve spent some time trying to figure out why the autostart, remote , and connect_back settings wont turn on. I\'ve typed in:
xdebug.remote_enable=1 xdebug.
Bit late answer maybe but here's how I solved this issue. For some reason MAMP conf files doesn't affect these settings, what I did was:
Go to /MAMP/bin/php/[phpX.X.XX ie your current version]/conf/php.ini and set it here.
