Contact form suddenly stopped sending emails

[curious]

I had a contact form that used to work properly. I changed no settings and suddenly it sends no emails to me nor to the one filling the contact form.
I tried changing the email address and updating everything but it's still not working.
Please help!

Thank you.

Check how you send emails, by PHP mail or by SMTP. If you haven't changed something the technical basis might have changed. Ask your hosting provider, some updates, other ports, authentication…
