We've just upgraded from 3.5.5 to 3.9 in replace of our usual administrator who would usually complete this and when opening the page we are getting this error message:
Class coursecat is now alias to autoloaded class core_course_category, course_in_list is an alias to core_course_list_element. Class coursecat_sortable_records is deprecated without replacement. Do not include coursecatlib.php
