Since about a week ago (today 19 May 2014) - when people use the contact form to send a message, I get no notification. Normally I would get an e-mail sent to say "contact from (site)". But not anymore.
I see under "settings" the option:
"Don't send me a mail if I get a message"
I have tried it with a tick and without a tick. But I don't get any notifications either way...
