Can't upgrade to Phalcon 1.3.0

You need to load PDO first before Phalcon.

In your computer, have a look at the /etc/php5/apache2filter/conf.d/ folder

The ini file that loads phalcon should be prefixed to a number higher than the one PDO is. So in my system I have:

20-pdo_mysql.ini 50-phalcon.ini

That should make it work :)

ini file does not exist at all

i've just deleted my virtualbox, i'll try to make it happen with vagrant https://github.com/phalcon/vagrant it's time to update not only Phalcon, but working environment too :) i hope official repository will work like a charm

I followed Nikolaos Dimopoulos tips and it works.

Just make a new file in /etc/php5/cli/conf.d/50-phalcon.ini and fill it with

; configuration for phalcon module

; priority=50

extension=phalcon.so

I am using ubuntu 14.04
