I have a multi-site installation of WordPress. I have created a local bbpress stylesheet in my theme that I want to load ONLY if the site administrator has activated the bbpress plugin. I am unclear on the conditional statement (e.g., “if(function_exists..”) to accomplish this as I do with other plugins that are optional. I have tried the following in my functions.php file but it throws an error. Please advise:

<?php 
//Load the bbpress styles if bbpress is installed //
if (class_exists( 'bbPress' ) ) {
?>
<link rel="stylesheet" id="bbpress_style" href="<?php echo get_stylesheet_directory_uri(); ?>/bbpress.css" type="text/css" media="screen" />
<? } ?>

Any input would be appreciated. Thank you!

Hmm, first of all the bbPress stylesheet shouldn’t be loading on sites that do not have bbPress activated. If it is, then there is a problem some where, because it shouldn’t be.

If you want to customize the bbPress CSS, you’ll want to:

Copy:

wp-content/plugins/bbpress/templates/default/css/bbpress.css

to:

wp-content/themes/[YOUR-THEME]/css/bbpress.css

When bbPress runs, it will load your theme’s bbpress.css instead of it’s own.
