Sadly I can`t get it to work. The image is set i “Header Image”. I have removed all of the widgets. No luck.
This is all the custom CSS, have I written something else that is overwriting this?
#header-left {
    float: none;
    text-align: center;
    width: 100%;
}
#site-logo {
    display: block;
    float: none;
    margin: 0 auto;
    width: auto;
}
#site-logo a {
    display: inline-block;
}
.category .page-header { display: none; }
.archive #content .hentry {
    height: 1%;
    overflow: hidden;
.archive .entry-header .entry-title {font-size: 20px; line-height: 0,5;}
#content article {
    margin-bottom: 15;
    padding-bottom: 0;
}
#content .entry-summary {
    padding: 0;
}
#content .entry-summary p {
    margin-bottom: 0;
}
#content .post .entry-header {
margin-bottom: 0;
}
.entry-meta { display: none; }
#hgroup-wrap, #site-logo {
    margin: 0 0 -10px;
    padding: 0;
}
Thank you!
