If you have ever enabled the meta widget in your WordPress sidebar you always come up with a few links. Usually you will get a log in link, 2 rss links and a WordPress.org link. Normally this is not an issue but if you would like to remove any or all of these, it is very simple. This is how you do it.
1. In your wp-includes folder, you will need to edit the default-widgets.php file.
2. Open default-widgets.php in your favorite web editor. The standard meta data starts at line 273. You will see an unordered list around line 295, this is where you want to do most of your editing.
3. Remove any link you want, just be sure to remove the list tags around each so you do not have any gaps.
That’s it!
