I'm using WordPress Version 2.8.3, and when I use the Lightword theme, there would be an error at the top of the page, and also the posts stop showing up aswell.
The error was, Warning: Parameter 1 to update_comment_type_cache() expected to be a reference, value given in C:\xampp\htdocs\wordpress\wp-includes\plugin.php on line 166.
Any help? Thanks. ;)
