Hi @Facultas

Hmmm… Could you please double check if your Crossref credentials (username and password) from the Crossref plugin settings are correct?

Best,

… wow, that hadn’t even occurred to me, thank you. You’re exactly right, somehow the login credentials saved in there weren’t correct anymore after the update. Fixed them and it worked perfectly again.
