    I’m receiving a strange error message in my error log:

    PHP Warning: trim() expects parameter 1 to be string, array given in /home/******/public_html/wp/wp-content/plugins/category-icons/category_icons.php on line 447

    Here is that line:

    if (trim($string) == 'Easily assign icons to your categories.') {
