I get this error due to one of the plugins which I rely on.
Notice: wp_enqueue_style was called incorrectly. Scripts and stylesshould not be registered or enqueued until the wp_enqueue_scripts,admin_enqueue_scripts, or init hooks.
What does this error mean and how do you fix it? Mind due that this is not a critical error. It only appears when I put WP into debug mode.
The full plugin-code is below.
It\'s one heck of a plug in that makes it a breeze to deal with the highly complicated and hierarchical cats. I\'m posting it not just for the sake of debugging where the bloddy error is but also to hope that it helps someone.

最合适的回答,由SO网友:Chip Bennett 整理而成
问题是wp_enqueue_style() 呼叫位于category_collapse() 的成员函数CategoryCollapse() 类，以及CategoryCollapse() 类正在由连接到plugins_loaded 行动挂钩。
这意味着wp_enqueue_style() 函数正在尝试在plugins_loaded hook, which fires before init, wp_enqueue_scripts, and admin_enqueue_scripts.
要修复此问题，请更换：
wp_enqueue_style( \'category-collapse\', plugins_url(\'/category-collapse/category-collapse.css\'), array(), \'2009.02.12\', \'screen\' );
。。。使用此选项：
function wpse49339_enqueue_styles() {
wp_enqueue_style( \'category-collapse\', plugins_url(\'/category-collapse/category-collapse.css\'), array(), \'2009.02.12\', \'screen\' );
}
add_action( \'wp_enqueue_scripts\', \'wpse49339_enqueue_styles\' );
那样的话
wp_enqueue_style() 呼叫将连接到
wp_enqueue_scripts 而不是直接向
plugins_loaded.
