Fatal error after upgrade

Hi,

I’m running Asterisk 11.18.0 and FreePBX 2.11.0beta1-2 on a Raspberry Pi 2.

I updated the system and received a fatal error with a binary dump from retrieve_conf.

FATAL ERROR

FreePBX is Unable to Continue

Attempted to load /var/www/html/admin/modules/sipsettings/Sipsettings.class.php but it didn’t define the class Sipsettings

Trace Back

This is a new install and I’m new to Asterisk and FreePBX.

Can anyone help me please?

Many thanks,

Simon
