I just updated Gommero and WordPress to the latest versions and I can no longer set the opacity of the background color. The website I'm working on is http://www.celebconn.com. This is what I had (and still have) in my Custom CSS:
font: 14px/1.5 'Trebuchet MS', sans-serif;
It appears that after the updates, I can set the background color in the Custom Background area, but how can I adjust the opacity without creating a gif image? Thanks!
