can you add stuff to the meta box?

Are you editing the right sidebar?
Are you using any caching plugins?
Have you clear out your browser’s cache?

If you haven’t read this yet, read it. Please provide your blog’s URL if possible.

Thank you!

My blog’s url is https://www.virtual-twilight.com/.

I’m editing the left sidebar, no caching plugins, tried clearing the cache, read the link. I’ve tried inserting <img src="https://www.virtual-twilight.com/images/rss-20.png" /> just about everywhere I could think to put it. (I know the image is too big, but I’ll fix that when I know how to put it in.) Nothing.

In fact, no matter what I try to put in that section, it has no effect. I tried plain text a few places, and that doesn’t work either.

Assuming that you haven’t edited the index.php file, the left side bar file should be sidebar.php (and the right sidebar is sidebar2.php)
The code your should be inserting/replacing after <li><?php wp_loginout(); ?></li> is: (I replaced the image with a smaller one)

<li><a href="<?php bloginfo('rss2_url'); ?>" title="Syndicate this site using RSS 2.0">Entries <abbr title="Really Simple Syndication">RSS</abbr></a> <img src="https://www.feedicons.com/images/feed-icon-14x14.png"/></li>
<li><a title="The latest comments to all posts in RSS" href="<?php bloginfo('comments_rss2_url'); ?>">Comments <abbr title="Really Simple Syndication">RSS</abbr></a> <img src="https://www.feedicons.com/images/feed-icon-14x14.png"/></li>

It would be better to do it in CSS, but that should do it for now.

That doesn’t work either, and it looks pretty much like what I was trying to do before. It’s like it just ignores anything I put in that box that wasn’t there to start with.

do your sidebars use widgets? If so, nothing you edit in sidebar.php will show when you have widgets in there.

Ah, yes. That would be the problem. Thanks.
