I opened up my header.php file and checked the line in question. It said exactly what you said it should say:
<link rel=”stylesheet” href=”<?php bloginfo(‘stylesheet_url’); ?>” type=”text/css” media=”screen” />
Also, I changed the theme to WordPress Classic, but it’s still having the same problems. I’m fairly sure I didn’t do anything to the site after I installed it. Is there any possibility that uploading it with GoLive did something to mess up the files? I’ve been told WYSIWYG editors have been known to do that with certain applications. Again, I appreciate the help.
