Freepbx 2.11.0 giving me php errors when installing and when I try to go to admin page

HI all… I’m trying to install freepbx 2.11.0 with asterisk 2.8 on a linux server running ubuntu 13.10. the thing is, is that I did several reinstalls, both with asterisk and with freepbx, trying different versions of freepbx but it is not working for me. I get the following error wen trying to visit my web interface of freepbx:
Warning: include_once(/etc/asterisk/freepbx.conf): failed to open stream: No such file or directory in /var/www/html/admin/config.php on line 106

Warning: include_once(): Failed opening ‘/etc/asterisk/freepbx.conf’ for inclusion (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/html/admin/config.php on line 106

Fatal error: Call to undefined function module_run_notification_checks() in /var/www/html/admin/config.php on line 139. Does anyone know what the probly is? If someone could help out with this, I would be very grateful. Thank you all.

What install guide are you following? The one from our wiki?

We do have installation instructions for Ubuntu in our wiki

Hi all. okay so I have installed the required stuff for it and reinstalled freepbx 2.11. but still giving me problems… when I do amportal, it’s giving me cannot create directory on /etc/asterisk even though it’s already created and I’m not sure what is going on with that or how to fix it. note: the php worning errors are still happening as well. is there a way to compleetly uninstall freepbx and start all over again? or is there another way to fix this problem? thanks all.

./install_amp --uninstall

Okay. guys, I’ve completely reinstalled freepbx and I’m still getting the php errors when I go to my admin interface. I’m not even sure why. The error is shown below this time:
Warning: require_once(/var/www/html/admin/libraries/ampuser.class.php): failed to open stream: Permission denied in /var/www/html/admin/config.php on line 72

Fatal error: require_once(): Failed opening required ‘/var/www/html/admin/libraries/ampuser.class.php’ (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/html/admin/config.php on line 72.
I’m not sure of what to do now sense I have reinstalled about a million times now… what dependencies am I missing? I do have all of the php dependencies installed and everything else… is there anything that I’m missing? and Yes, I have followed the guyed on the wiki. Do I need to change the include path of where everything is installed at and if so, how do I do that in regards to php5 and php pear… note: I’m using ubuntu 13.10 not ubuntu 13.04. Pluss… how would I find out where php5 and php pear is installed at? I’m sorry for asking this many questions… but I really want to get this working… and I can’t really figure out why this is happening to me… thanks all.
