• I did a fresh install of WordPress and then installed the gradebook plugin from the plugins menu.
    I get the below error at the top of every page in the WordPress admin area. I have WordPress version 4.5.3 and PHP version 5.5.22. Is there a way I can fix this?

    Warning: array_keys() expects parameter 1 to be array, boolean given in /**PATH TO WORDPRESS**/wp-content/plugins/an-gradebook/GradeBook.php on line 34
