Hello,
This is because the features module is unable to load correctly, since it’s trying to include some features that doesn’t exist, to fix it comment out the custom_atxfer and custom_blindxfer custom features in /etc/asterisk/vitalpbx/features__10-application-map.conf
nano /etc/asterisk/vitalpbx/features__10-application-map.conf
then reload the features module
asterisk -x"module reload features"
I hope that VitalPBX will fix this in the next release.
