Thanks CK
but I always have the same message :

Fatal error: Call to undefined function is_plugin_active() in C:\xampp\htdocs\wordpress\wp-content\themes\veritas\functions.php on line 27

PS: I am using WP 2.6 on a local install (xampp).

Have a good day.

@micheal if you are using wordpress version less than 2.5 you should add the following code inside your theme’s functions.php

function is_plugin_active($plugin_filename){
 $plugins = get_option('active_plugins');
 if( !is_array($plugins) ) settype($plugins,'array');
 return ( in_array($plugin_filename, $plugins) ) ;
}
