Great product, but recently stopped working
About a month ago, contact form entries stopped coming in via email and I just checked the system and it displayed “Mail sending failed! (Could not instantiate mail function.)” in the Mail Status page
Very good
It works fine as it does what it is supposed to.
Great, and simple way to add form functionality
