can you try the following patch:

Index: retrieve_conf

+       }
+}

 ini_set('error_reporting', E_ALL & ~E_NOTICE);
 
 define("AMP_CONF", "/etc/amportal.conf");

You appear not to have the localization environment setup (the _() function) and this will fix that. As far as not being able to run as asterisk, that is problematic and you will want to get to root cause on that.

But please try the above patch as you have pointed out a valid bug that should be addressed which is to define the function if it is not in your environment.

the problem is with Asterisk and how it sets permissions on some voicemail files (600). Until we get to the point where we have a daemon (in the plans) it needs to run as asterisk or you will have problems with some functionality.

However - did the above patch fix the _() problem for you, feedback would be appreciated.

I am still getting the error message after applying the patch. FreePBX notice: retrieve_conf failed, config not appliedReload failed because retrieve_conf encountered an error: 255

I tried su - asterisk ./retrieve_conf but I am getting an error on line 3 and line 11. This happened right after the upgrade this morning.

UPDATE NOTICE: There are 3 modules available for online upgrades framework 2.4.0beta1.1 (current: 2.4.0beta1.0) parking 2.4.0.2 (current: 2.4.0.1) core 2.4.0beta1.2 (current: 2.4.0beta1.1)

bad timing - try again, make sure it had been 10 minutes since the last time you tried.

I got this error and determined that PHP was running out of memory.
I increased this line and it worked fine after that:

#memory_limit = 16M ; Maximum amount of memory a script may consume
memory_limit = 64M ; Maximum amount of memory a script may consume
