In my case, I had this problem, because my htacces has these lines:

RewriteEngine on
RewriteRule ^(.*)\.css$ /wp-content/plugins/script-compressor/jscsscomp.php?q=$1.css [NC,L]

I’ve solved my problem eliminating these lines from my .htaccess.

I solve my problem, renaming plugins folder to plugins.hold, creating a new empty plugins folder and deleting this line from my wp-config.php:
define ('COOKIE_DOMAIN', 'www.mydomain.com');

ralev,

here is my solution: “an automatic condition script that could be attached to the main category.php and checks if there’s just one post in the category and redirects.”

<?php
	if(have_posts()) :
		$category = get_the_category();
		if ($category[0]->category_count == 1) :
			while (have_posts()) : the_post();
			wp_redirect(get_permalink($post->ID));
			endwhile;
		else :
			include(TEMPLATEPATH . '/index.php');
		endif;
	endif;
?>

diotima,

If the solution posted by samboll doesn’t work, please reinstall the plugin because i’ve made some updates on it.

Thanks, best regards,
