Thanks to “Kjell Bublitz” on Ruby on Rails: Spinoffs, I have a solution. Here it is if anyone needs it:
<a href="javascript:Effect.Combo('file<?php the_ID(); ?>', {duration: 0.5});" title="Filed Under"><img src="<?php echo bloginfo('template_url'); ?>/images/file.gif" /></a>
<div id="file<?php the_ID(); ?>" style="display: none;">
<?php echo ''; _e(get_the_category_list(', ')) ?></div>
Thanks to everyone.
Deactivated all my plugins, tried everything in every thread/post, still nothing.
This is no small problem.
I guess WordPress can’t/won’t fix it.
Time to move on to other software, WordPress’s days are over.
Same here! What’s going on!
