Captcha refresh not working.

It's a problem with your theme CSS. The new CAPTCHA image is there, it just has the opacity set to zero. You can find the offending CSS rule on line 41 of your theme's main.css file.

[css]
/* #To Fade In On Load
================================================== */

	#nav-responsive,
	#wrapper header,
	#hero,
	#sidebar,
	#main,
	#main img {
		opacity:0;
	}

if you disable that, the CAPTCHA image refreshes and displays properly.

You can always try overriding it with better inheritance by placing something like this at the end of your theme stylesheet or wherever you put your custom CSS rules.

[css]
body .gform_wrapper img {
	opacity:1.0 !important;
}
