Send button not working, and not receiving emails

I’m using your plugin and finding a couple of issues:
-I’m not receiving an email when I run a test by populating the fields and pressing send.
-I have also noticed that the send button does not work when I have the reCaptcha on the form. But when the reCaptcha is taken off, the button works.
-Your Message area is not changing size when I add in attributes to the tag to increase the size.

Can you please help?
