Cant get Contact 7 to work on my site

Hi, I cant seem to get the form to work for this website:
https://www.beyondthecamp.org/contact-us/

It says “There was an error trying to send your message. Please try again later.” when I try to submit.

Also, the Message textarea is white text – different from the other text areas. How do I fix it to be black?
