I updated from amp 1.10.010 to freepbx 2.2.beta5, when running the update script, the following error output is shown short before the end:
Checking for PEAR DB..OK
Checking for PEAR Console::Getopt..OK
Running module install.php and install.sql scripts
Checking for /etc/amportal.conf..OK
Reading /etc/amportal.conf..OK

<b>Fatal error</b>: Call to undefined function: core_users2astdb() in <b>/var/lib/asterisk/bin/retrieve_conf</b> on line <b>368</b><br />
Generating AMP configs..OK
Restarting Flash Operator Panel..OK
I don't know whether this broke sth. as at least at a first glance, the configuration looks good. All the rest of the output seems to be ok.
