I am having the same problems trying to run with a non-asterisk web user (in my case user is called ‘pbx’). I’ve also tried adding the web user to the asterisk group but this makes no difference as a user isn’t allowed to edit the crontab of another user.
Here is the error I am getting despite both AMPASTERISKWEBGROUP and AMPASTERISKWEBUSER in /etc/amportal.conf being set to ‘pbx’:

Several other users have reported similar problems while trying to run the web interface with anything other than asterisk as the user [put http:// on these as I can’t post links as new user]:
issues.freepbx.org/browse/FREEPBX-2727
The Asterisk service itself is running as asterisk user. FreePBX is 12.0.43 running on Ubuntu 14.04.
