Notifications via email

I have been on a forumotion website for over a year, and have never had any problems with my email notifications before. But recently I have not been getting notifications about PMs I have received, or any topic replies that have been posted. I haven't got any messages since the new year began, I think, and I've been active, along with other users on the website. I don't know what's going on or why it is, please help me.

This problem is also occurring on another forumotion website, the one I own and am Administrator on.

Other info: I am an administrator on this website along with another admin and two mods. As far as I am aware, no-one seems too be having any problems... :S

You can enable it in https://help.forumotion.com/profile?mode=editprofile&page_profil=notifications

They are all ticked, so I should be getting messages, but I am not.
