How do I Remove Sideboxes Titles?

[Get Em Fast]

blue, all you have to do, is got to includes/languages/english.php and edit each box heading you don't want shown, such as categories:

// categories box text in sideboxes/categories.php
define('BOX_HEADING_CATEGORIES', 'Categories');

Just delete the Categories (highlighted) to look like:

// categories box text in sideboxes/categories.php
define('BOX_HEADING_CATEGORIES', '');

The heading will now be gone.
Hope this helps.
