Through out our discussion and with help from fire bug I found right at once following code in the header(!) from the header.php:
<style type="text/css">
#wrapper, #access, #colophon, #branding, #main { width:1320px ;}
#access .menu-header, div.menu {width:1308px ;}
#content { width:730px;float:right;margin:0px 290px 0 -1270px;display:block;}
#primary {width:260px;float:left;padding-left:0px;border:none;border-right:1px dashed #EEE;padding-right:20px;}
#secondary {width:260px;float:right;}
#primary .widget-title { -moz-border-radius:0 10px 0 0; -webkit-border-radius:0 10px 0 0;border-radius:0 10px 0 0 ; text-align:right;padding-right:15px;width:100%;margin-left:-8px;} #content p, #content ul, #content ol {
font-size:14px;
}
#branding { background-position:50% 0 !important;} #access ul li { background-color:#FECC00} #primary { background-color:} #secondary { background-color:} * , .widget-title {font-family:Segoe UI, Arial, sans-serif ; } #content h1.entry-title a, #content h2.entry-title a, #content h1.entry-title , #content h2.entry-title {font-family:Georgia, Times New Roman, Times, serif ; } .widget-area * {font-family:Helvetica, sans-serif ; } .entry-content h1, .entry-content h2, .entry-content h3, .entry-content h4, .entry-content h5, .entry-content h6 {font-family:Georgia, Times New Roman, Times, serif ; } .nocomments, .nocomments2 {display:none;} body { background-color:#cd1013 !important ;} #header { background-color:transparent ;} #footer { background-color:transparent ;} #footer2 { background-color:transparent ;} #site-title span a { color:#0D85CC ;} #site-description { color:#999999 ;} #content p, #content ul, #content ol { color:#333333 ;} .widget-area a:link, .widget-area a:visited, a:link, a:visited ,#searchform #s:hover , #container #s:hover, #access a:hover, #wp-calendar tbody td a , #site-info a ,#site-copyright a, #access li:hover > a, #access ul ul :hover > a { color:#fff;} a:hover, .entry-meta a:hover, .entry-utility a:hover , .widget-area a:hover { color:#bbb ;} #content .entry-title a, #content .entry-title, #content h1, #content h2, #content h3, #content h4, #content h5, #content h6{ color:#444444 ;} #content .entry-title a:hover { color:#000000 ;} .widget-title,#footer-widget-area .widget-title { background-color:#444444 ;} .widget-title { color:#2EA5FD ;} #footer-widget-area .widget-title { color:#0C85CD ; ;} #footer-widget-area a { color:#666666 ;} #footer-widget-area a:hover { color:#888888 ;} .entry-meta .entry-time {display:none;} #branding {background:url("http://xyz.com/wp-content/uploads/2012/12/foto_750x500.png") no-repeat;
width:880px; height:559px;}
</style>
installed with header_hook. Where I found that? .. forward searching follows one result in costum-styles.php(main css style from my theme = mantra): #branding { background-position:50% 0 !important;}
to whome it may concern
