When I upgraded my blog to WordPress 2.3, I found that I can use tags that I have not used it ever before, so there is a problem: The blog theme does not show the tags when I write a new post. The cause is that the them k2 use the UTW system to show tags. so it is natural to show tags if use WP 2.3. I changed some of the source code in theloop.php:
Using function get_the_tags() is to get whether the post has a tag or more, and using the function the_tags('BEFORE','SEPERATE ','END') is to show the tags, where BEFORE, SEPERATE, END mean symbols to show tags before tags, seperating symbol, and after the tags.
