Author Name Dropping Below Line

The issue you’re having comes from your theme styles. the div below adds a padding-top

to all a-tags/links in your sidebar including the one you inquired about.

.widget li a {
    padding: 4px 0; THIS ONE
    display: inline-block;
    vertical-align: top;
}

Place this in your theme stylesheet and you should be straight.

div.rss_content small a{
  padding-top:0 !important;
}
