Exclude Category from Homepage

I would like this same plugin. Any guidance would be much appreciated!

Category Overload hasn’t been tested on 2.5 by the author, but it seems worth a shot.

I tried the template tag. But no luck.

EDIT: I tried the Category Overload plugin, but then it said I had no categories.

I got it to work through WordPress’s theme editor.
It didn’t work when I added it to the index.php file though.

Either way it’s working now. 🙂

The Answer is on this page:

Here’s the quote:

Exclude Categories From Your Home Page

Placing this code in your index.php file will cause your home page to display posts from all categories except category ID 3.

<?php
if (is_home()) {
query_posts(“cat=-3”);
}
?>

You can also add some more categories to the exclude-list(tested with WP 2.1.2):

<?php
if (is_home()) {
query_posts(“cat=-1,-2,-3”);
}
?>
