Hi @citizenfive,

Is this a result of a previous upgrade or change to your journal site?

Yeah. Recently we updated our journal from 3.1.1.0 to 3.1.1.4.
Should I update to the latest version?

Hi @citizenfive,

It does seem that the upgrade was not successful. Are there any errors in your PHP log?

Kind Regards,
