Installed Module & System updates, now cannot apply settings

Hello Everyone,

Just installed system & module updates, now I cannot apply settings, I get this message:

exit: 255
Unable to continue. Call to undefined function FreePBX\modules\Core\Drivers\version_min() in /var/www/html/admin/modules/core/ on line 499
#0 /var/www/html/admin/libraries/Composer/vendor/filp/whoops/src/Whoops/Run.php(383): Whoops\Run->handleError(1, 'Call to undefin...', '/var/www/html/a...', 499)
#1 [internal function]: Whoops\Run->handleShutdown()
#2 {main}

And on the dashboard I get:

retrieve_conf failed, config not applied
Reload failed because retrieve_conf encountered an error: 255 

I believe the only system update was the sysadmin package.

PBX Firmware: 12.7.6-1910-1.sng7

Have a look here:


Damn, not sure how I missed that, thank you!

As a temporary solution to the problem, I commented out the lines in PJSip.class.php

Had the same problem and applied the ‘edge’ fix and problem solved.

But now, trying: System Updates > Check Online gives

and the Refresh Page button in the top right corner starts to flash - till I reload the page.

Hi @LesD,
Issue has been fixed. Now you have to update the sysadmin RPM.
Check it.


Sorry, but how do I do that?

@LesD Run “yum update” on the cli to update the sysadmin rpm.

Thank you very much - working.
