Minor issue with logging out of FOG web UI: HTTP ERROR 500

[Fog_Newb]

When Logging out of the Web UI I get a “This page isn’t working
10.1.1.100 is currently unable to handle this request.
HTTP ERROR 500”

To duplicate
Click Log Out Of Fog, which directs to this URL http://[ipaddressoffogserver/fog/management/index.php?node=logout

Gives HTTP ERROR 500

Tried on Brave and Firefox
