There was a problem sending an email message. Please try again later, or contact your system administrator. What should I do?

The system is not sending emails to authors, reviewers, etc. Whenever, I assign a paper to reviewers or editors, this message pops. Please see the message on right top corner of the image attached below.

We are currently using OJS 3.3.0.8

Hi @Dr_Dharen_Kumar_Pand

you’ll need to talk to the systems administrator for the server that is hosting your installation. There will be detailed error messages in the Apache error log for this.

Thank you for the suggestion. I will get back after this.
