OJS 3.1.2 - can't schedule article for publication

Ok, similar to the problem where saving metadata was not possible because of OpenAir plugin (see post After update to 3.1.2 the new submission not saved the metadata - #4 by Anuj_Mittal) i found out that here problem lies in ORCID plugin. After i disabled that plugin all works fine.

EDIT: i installed new version of ORCID plugin compatible with OJS 3.1.2 so i hope this will work now.

Regards.
