I was recently made aware that people have been trying to contact me through the 'Contact Us' form, but I am not receiving the emails. It was working at one point and I haven't changed any of the settings, so I have no idea why it's not working now. Can anybody help me?

I am using Zen Cart 1.3.7.1 and my webhost is ipowerweb. Email transport method is PHP.

Contact page is here:

Thanks
