[Observium] No pages after loging in

Hi list,

Simple problem statement, as per the subject, I get no pages once I log into Observium.

More Background.

I'm running CE 17.9 edition and have done sucessfully since it's release. I have however update my OS to Ubuntu 18.04 and PHP-7.2.

In searching I saw http://jira.observium.org/browse/OBS-2537 and assume my CE issue is a PHP7.2 related one.

Is there anyway I can confirm this is a PHP7.2 issue? This is just on my home network (because I can), so nothing urgent and if the fix is "wait until the next release" then I'm good with that.
