5097,Tag-related issues with wp_rewrite in 2.3,kaeru,anonymous,"I'm having trouble getting tagging to work in 2.3. I've upgraded my blog without trouble. I have converted all my categories to tags, which went fine as well. The issue is when I try to update my permalinks for tags or display tags on my blog. 

In the permalinks panel, it throws the following error after I try to specify a tag base.

'''Fatal error: Call to undefined method WP_Rewrite::set_tag_base() in /home/.pug/karsalfrink/leapfrog.nl/blog/wp-admin/options-permalink.php on line 81
'''

On the blog, it throws the following error for the template tag 
{{{
<p><?php the_tags(); ?></p>
}}}

'''Fatal error: Call to undefined method WP_Rewrite::get_tag_permastruct() in /home/.pug/karsalfrink/leapfrog.nl/blog/wp-includes/category-template.php on line 423
'''

And this error on the archive page where I try to display a default tag cloud using 
{{{
<?php wp_tag_cloud(''); ?>
}}}

'''Fatal error: Call to undefined method WP_Rewrite::get_tag_permastruct() in /home/.pug/karsalfrink/leapfrog.nl/blog/wp-includes/category-template.php on line 423
'''

I've done some digging and found this page:

[http://codex.wordpress.org/Function_Reference/WP_Rewrite]

Where it says:

  It's defined in wp-includes/wp-classes.php and a global singleton, $wp_rewrite, is initialised in wp-settings.php.

I can find the initialisation in wp-settings.php, but there is no wp-classes.php in my wp-includes directory. Furthermore, I cannot find the file in the WordPress distribution I downloaded on the morning of sep 28.

Finally, I have verified this is not a theme issue by testing one of the prepackaged themes. The default theme throws exactly the same errors as my own.

Any help would be greatly appreciated.",defect (bug),closed,normal,,General,2.3,normal,invalid,,
