I've checked with my host and there's no error logs. I have smtp plugin installed with correct settings and have the latest version of WP Foro installed.
I'm getting the internal alert when there's a new message, but no email is being sent. I already checks spam and trash.
This is a site specific issue for sure, because this addon works fine and sends emails on hundreds of websites. There is no any bug in email sender functions.
Please check these points:
1. Make sure the Email Notification is enabled in PM settings. The settings page is located in Dashboard > Forums > Settings > Addons > Private Messages Tab.
2. Make sure the Email Notification button is turned on for the conversation you're currently testing.
3. Make sure you receive emails from WordPress and wpForo. This maybe a global email sending issue.
4. Test it using other users and emails.
5. Please disable all plugins, especially the SMTP plugin and test it again.
I double checked and everything was turned on like you showed and I turned off all the other plugins and tested it again and still no email. Any other ideas to get this working?
