Wordpress version 3.4.1
Ata version 3.7.3

I made some changes in HTML/CSS inserts (see below) and now my header image is no longer clickable. In ATO-->Header Image-->Make clickable is set to "Yes." Any suggestions would be appreciated. Thanks.

/* CONTROLS THE HEADER IMAGE ON SPECIFIC PAGES */

div#imagecontainer { 
background-position:left top;
background-repeat:no-repeat;
height:125px;
margin:0;
padding:0;
position:relative;
}

/* SHOWS THIS HEADER IMAGE BY DEFAULT */
body div#imagecontainer {
background-image: url(http://www.ncchurches.org/wp-content/themes/atahualpa351/images/header/NCCC_header.jpg) !important;
}

/* OVERRIDES THE DEFAULT IMAGE */
body.page-id-6404 div#imagecontainer {
background-image: url(http://www.ncchurches.org/wp-content/uploads/2011/12/lectionary06.jpg) !important; 
}

body.page-id-6406 div#imagecontainer {
background-image: url(http://www.ncchurches.org/wp-content/uploads/2011/12/lectionary06.jpg) !important; 
}

put the default image in teh atahualpa/images/header folder and then use the css to override it on the other pages

I moved the images to the correct folder and updated the URL in the CSS insert, but it's still not clickable. Is there something wrong with my CSS? Am I overriding it correctly?

go to ato->export/import settings - export your settings and attach them to a reply
you should also take out this line of css

/* SHOWS THIS HEADER IMAGE BY DEFAULT */
body div#imagecontainer {
background-image: url(http://www.ncchurches.org/wp-content/themes/atahualpa/images/header/NCCC_header.jpg) !important;
