Warning: array_keys() expects parameter 1 to be array,

Question

I am getting the following warnings:

Warning: array_keys() expects parameter 1 to be array, object given in /home/inin3486/public_html/wordpress/wp-conten

Answer 1

Simply change the code from line 1 to 14:

function wpcrown_wpcss_loaded() {

    // Return the lowest priority number from all the functions that hook into wp_head
    global $wp_filter;
    //$lowest_priority = max(array_keys($wp_filter['wp_head'])); (I made this comment)

    add_action('wp_head', 'wpcrown_wpcss_head', $lowest_priority + 1);

    $arr = $wp_filter['wp_head'];}

add_action('wp_head', "wpcrown_wpcss_loaded",$lowest_priority);
