I am having problems with the ContactForm plugin. It stopped sending mails. I'm getting following error after submitting "Could not instantiate mail function."
PHPMail should be working. I checked with a simple php outside of craft. Also the sendmail option in ContactForm does not work.
I don't now when it stopped working. I thought when I added a second locale, so I added a new test single including a from with only one locale. But that single cannot send the form, too.
