Admin comment color on blogs

It really how you’re listing your comments and what, if any, other CSS is at work on your site. A link to one of your pages that includes an author comment might help.

https://www.band-geek.net/?p=801 Here’s a link to a page that contains an author comment (the last one)

Your CSS would probably work but for the fact that there’s a problem with your theme. Where the various comment classes should be generated (including bypostauthor), I found the following:

Warning: join() [function.join]: Invalid arguments passed in /f1/content/band-geek/public/wp-content/themes/k2/app/includes/info.php on line 735

.comments input[type=text], .comments textarea {
	font-size: 12px;
	padding: 3px;
	color: #777;
	}

input[type=text]:focus, textarea:focus {
	background: #fff;
	color: #333;
	border-color: #666;
	}

.comments form input[type=text] {
	width: 45%;
	margin: 5px 5px 1px 0;
	}

.comments textarea {
	width: 100%;
	margin: 10px 0;
	}

.comments form #submit {
	float: right;
	}

#footer {
	clear: both;
	margin: 0 auto;
	padding: 20px 0 40px;
	text-align: center;
	color: #777;
	}

#footer p {
	line-height: 1.6em;
	}

#footer a {
	color: #888;
	border-bottom: 1px solid #ccc;
	font-weight: bold;
	}

#footer a:hover {
	border: none;
	text-decoration: none;
	color: #000;
	}

#footer .wp-version,
#footer .k2-version {
	display: none;
	padding-left: 0.3em;
	}

.footerstats {
	display: none;
}

This is what my code looks like starting from line 735, without the ” of course. bypostauthor isn’t even in there… this is what the whole comment section looks like:

No added CSS will work properly until you get the error I mentioned above sorted.

How would I go about fixing the theme? Reinstall?

If you can, yes.
