Call to undefined method UsageStatsTemporaryRecordDAO::getNextByLoadId() + white screen of death

My new host (Kualo) says the blank screens we’re getting since migrating to their hosting (e.g. when opening a submission) are being caused by the error below, but I can’t find any previous examples of this error.

Can I disable the usageStats plugin or something? Upgrading OJS also appears to be broken on the new host (it’s on 3.1.1.4 and I wondered if updating would fix the issue).

Hi @matthewbarr,

I can’t speak to the specifics of this particular error, but I should note that 3.1 is quite outdated and no longer supported, so upgrading is highly recommended. It may also resolve your issue.
