It is not necessary to change the settings from Php.ini, you can easily do it from below method:
Goto :

Open, settings.php which you should have renamed from default.settings.php
Edit the file, and put this on the very beginning of file:
ini_set('max_execution_time', 0);
Run, it will work, no need to restart your apache service. Cheers :)
