Comment:
This patch didn't work when I used it on my blog. The tags are still
numbers despite following steps to use this patch per the WP Support
Forum. Suggest another look at this patch to ensure it works in all
cases.
Can verify that it doesn't work on my blog at
[http://wargamingforums.com]. Patched WordPress.php file is shown below.
