Hello, another two problems. If you see here

By author should be in the left position near post profile instead of right position and look admin has black background that overlapping its username. I will be happy to remove black background. Hope someone can help me

Thanks

Search and replace

Code:

.postprofile dt strong

by

Code:

.postprofile dt a :not(span) strong

Search and remove right: -22em; in this CSS

Code:

.postbody .author {
    line-height: 1.2em;
    margin: 0 15em .6em 0;
    padding: 2px!important;
    position: relative;
    right: -22em;
    text-align: center;
    width: 230px;
}

You should better learn basic CSS and HTML for modifying these very basic layout, instead of opening a tons of topic.
