I would like to apologise to all of you who came here looking for documentation, plugins, or just a read. It seems that I screwed up when trying to add, what I call, "quick admin links" to posts. It's just some links that allow you to delete/edit comments and/or posts. Unfortunately I did the following with the "the_content" filter:

if (!current_user_can('edit_post', $post->ID)) {
    return;
}

Of course, that meant that all of you who were not logged in to my site, could not see any post nor comment contents, while I could see them just fine. And this brings up a good point. When using filters, remember to return the original content passed to your function, or you'll end up like me, contentless. ;)

Here's what I should have done and now have done:

if (!current_user_can('edit_post', $post->ID)) {
    return $content;
}

Again, sorry to all who came looking for content. hahahah
