In Moodle 3.1.3+ we are having issues with the assignment grading interface not loading or not loading correctly. After opening the grading interface through the Grade button, it hangs in a 'loading' status and does not display:
- name of student
- student list
- assignment converted to pdf for annotation
- right column for comments, grade and feedback
This could be due to not correctly handling the caching of documents to be graded in the interface. Since this is a critical component of Moodle for us, we would like to resolve it as soon as possible.
