I am trying to replace the sidebox headings background. I have followed the instructions indicated here:

http://www.zen-cart.com/content.php?...sidebox-header

Right now my sidebox headings backgrounds in the stylesheet are:
Code:
h3.rightBoxHeading, h3.leftBoxHeading  {
background-color:#79A0BD;
I uploaded a box-title-bg.jpg image and changed the above in the stylesheet to be:
Code:
h3.rightBoxHeading, h3.leftBoxHeading  {
background:transparent url('../images/box-title-bg.jpg') center center no-repeat;
… and it does not work.
Do you know what I am doing wrong ?

I am using ZC 1.5: see a link to the site here: http://goo.gl/ylDnt
