Some notices messages which can maybe fixed

[uniterre]

Hi,

I use wordpress multisite on my own cms and I notice there are many notice messages when I load WP (include($wppath."includes/wp.inc.php") :

1) Declaration of Walker_Category::start_el() should be compatible with that of Walker::start_el()) in /wp-includes/category-template.php line 902

2) Declaration of WP_Scripts::set_group() should be compatible with that of WP_Dependencies::set_group()) in wp-includes/class.wp-scripts.php

3) Declaration of Walker_Nav_Menu::start_el() should be compatible with that of Walker::start_el()) in wp-includes/nav-menu-template.php

4) is_a(): Deprecated. Please use the instanceof operator) dans le fichier wp-includes/capabilities.php

Hope it helps
Regards,
Alexandre

Please update to PHP 5.3, where is_a() is no longer deprecated.

The others appear to be valid issues:
