DOI, several jounals problem

i have 2 journals opened at one installation of OJS.
First journal have assigned DOI, and are opened settings page for DOI. Second journal gives me error that:

“Plugin requirements not met
Articles are not selected for DOI assignment in the DOI public identifier plugin, so there is no deposit or export possibility in this plugin.”

DOI plugin and crossref plugin are both active. Coockies and caches are cleared. But i cant assighn doi to second journal

Hi @redukr,

Which version of OJS are you using?
From the first impression it looks like that for the first journal the DOI is configured and for the second not.

@primozs is installed.
i can’t find where to configure DOI for second journal
