Same here. chris-moody.com. No send button appears.
I had this issue on my site tonight too – chris-moody.com
It was actually the theme causing the issue. My CSS file had a minimum height set for iframes. Open your CSS file in the Appearance Editor and search for iframe. Mine had a minimum height of 250px.
Obviously, this created a huge space. I changed that to 20px and then everything was perfect.
i just found out what was causing this for me.
the newest wp-config has the keys where you can input information inside the quotation marks.
i made the dumb mistake of using two punctuation symbols (an ! and you’re) and that was killing the install (or reinstall) for that matter.
it may be something very obvious to most, but i screwed it up and haven’t read that documented. hopefully that can help someone because it interpreted it as code and threw everything off.
