I've discovered an issue on my wordpress site - no emails are being sent - for new user creation, when comments are written, or when a contact form (contact form 7 or jetpack) are filled out. The emails are not sent to spam or regular inbox.
I even installed WP fresh and was able to get emails to send, but when I set the WP URL and Site URL to make the website live, emails stop working.
So my Wordpress site is installed at http://www.stephenemlund.com/icphotobooth2 - but the live domain name (and what I've changed WP URL and Site URL to is http://www.iowacityphotobooth.com
I've tried installing and activating WP-Mail SMTP (and just changing the 'from email') and this doesn't work - I haven't tried changing the host/port because I'm not sure what to put there - but changing these on my initial WP install (before reinstalling) didn't help.
I'm using Godaddy Shared Hosting on Linux, btw.
What could cause WP emails to stop sending when a the WP URL and/or Site URL is changed?
