Hi Evilmc

You can fix/change this with some custom CSS. If you navigate to Appearance > Custom CSS, you’ll get our custom CSS editor. Just add the following code.

/* Buttons */

button,
html input[type="button"],
input[type="reset"],
input[type="submit"] {
	border: none !important;
  	background: #ffffff !important; /* Set this to your button background color. */
  	color: #646464; /* Set this to your button text color. */
  	-webkit-box-shadow:none;
  	-moz-box-shadow: none;
  	box-shadow: none;
  	text-shadow: none;
}
button:hover,
html input[type="button"]:hover,
input[type="reset"]:hover,
input[type="submit"]:hover {
  /* Button hover style */
  border: none !important;
  background: #ffffff !important; /* Set this to your button background hover color. */
}
button:focus,
html input[type="button"]:focus,
input[type="reset"]:focus,
input[type="submit"]:focus,
button:active,
html input[type="button"]:active,
input[type="reset"]:active,
input[type="submit"]:active {
  /* Button click style */
  border: none !important;
  box-shadow: none !important;
}

See my notes. Where I’ve said a background or color must be set, insert our background and text color.
