I’m using the child theme of Omega, “shopping”… and I’ve hidden the title on my pages.
I used Firebug for Firefox to see what class is used in my theme… it was called entry-title.
when you know what the css class is for your heading title, you can then put this in your custom css panel in your theme admin area (you would change .entry-title to whatever your title class is on your theme… it may be the same…
/* comment out the page title from showing */
.entry-title {
display: none;
}
