In OJS 3.4.0.6, when assigning a reviewer to an article, the email is not sent to the reviewer, but the notification is shown in the panel. Other emails related to registration and … are sent correctly.
Hi @Jpour_Mail,
Do you know if the recipient’s address is a gmail or yahoo address. If so, this thread offers some suggestions: Reviewer invitation email is not reaching the reviewer's email - OJS 3.4.0.5 - #2 by kerimsarigul
