After installation on debian wheezy of freepbx 2.11 i have this error on my apache logs (and 2 warnings) :
PHP Warning: include_once(/etc/asterisk/freepbx.conf): failed to open stream: No such file or directory in /xxxx/xxxx/xxxx/xxxx/admin/config.php on line 110
PHP Warning: include_once(): Failed opening ‘/etc/asterisk/freepbx.conf’ for inclusion (include_path=’.:/usr/share/php:/usr/share/pear’) in /xxxx/xxxx/xxxx/xxxx/admin/config.php on line 110
PHP Fatal error: Call to undefined function module_run_notification_checks() in /xxxx/xxxx/xxxx/xxxx/admin/config.php on line 143
Problem solved, i installed freepbx and configure my virtual host apache correctly with module mpm_itk_module too use asterisk user and not www-data etc
