Back Up your template.

Search for the word "breadcrumbs" and find something like:

/* Breadcrumbs */
.breadcrumbs{line-height:1.6em;background-color:#FFF;padding:12px 14px;margin:7.5px 4px 10px 0;font:bold 12px Arial;color:#666;border:1px solid #DDD;}
.breadcrumbs span a {color:#666;}
.breadcrumbs a:hover {text-decoration:none;color:#3498DB;}

@media only screen and (max-width:1066px){

.breadcrumbs {
    width: 100%;
}

}

This is the css. Replace all this with the:

/* Breadcrumb */
.breadcrumbs{background:#fff;line-height:1.2em;width:auto;overflow:hidden;margin:0;padding:10px 0;border-top:1px solid #dedede;border-bottom:1px solid #dedede;font-size:80%;color:#888;font-weight:400;text-overflow:ellipsis;-webkit-text-overflow:ellipsis;white-space:nowrap}
.breadcrumbs a{display:inline-block;text-decoration:none;transition:all .3s ease-in-out;color:#666;font-weight:400}
.breadcrumbs a:hover{color:#11589D}
.breadcrumbs svg{width:16px;height:16px;vertical-align:-4px}
.breadcrumbs svg path{fill:#666}

Find from        <b:includable id='breadcrumb' var='posts'>

to               </b:includable>

and replace all with:

          <b:includable id='breadcrumb' var='posts'>
