Error when logging in, /usr/share/webapps/icingaweb2/library/Icinga/Authentication/User/

Icinga Web

Hi,
Having problems logging into icingaweb2; does anyone have an idea how to solve this. I’m using Arch so it’s a very recent 8.2.6 version of PHP. I’m using nginx and postgres. I’ve included the error and icinga2 -v below.
Thanks
James
