I am having the same problem reported here (2009 in the old forum) in a OJS 2.4.2 installation. By concluding the review of a submission, the editor rejects the paper recording the decision in the submission review page. After doing this, the paper remains listed in the editor “In review” page. I think it should be directly moved to the “Archive”. In order to do this, the editor must return to the summary of article page and click on the “reject and archive”.
Any hint on that?
