Sure! Looks like you already tried with some custom CSS.
For the homepage (blog), archive, and search pages, remove this:
.home .author-img, .home span.author.vcard, .home div.entry-meta span.sep {
display: none;
}
And add this instead:
.blog .entry-meta, .archive .entry-meta, .search .entry-meta {
visibility: hidden;
}
For single posts, remove this:
.single-post .entry-meta .author-img,.single-post .entry-meta .author {
display: none;
}
.entry-author {
display: none;
}
And add this instead:
.single .entry-author {
display: none;
}
Let me know how it goes!
