Everyone
The handful of things that actually go wrong, and what each one means.
Nothing works without one. Admin → Academic years & terms, then Set current on the term you are in. If the year exists but a term is missing, that page offers to add the missing ones.
Almost always the grading mode. Check Classes → Grading for that class, and check whether that term has its own settings — the box at the top of the page.
If the term you are looking at has its own grading settings, editing the class default does not touch it. The Grading page names any term this applies to. Either edit that term, or put it back on the class's usual settings using the button there.
A subject teacher only sees the subject-and-stream pairs they are assigned. Admin → Staff and parent logins, open them, and check the assignments. A class teacher must be set as class teacher of that stream under Class teachers.
One bad cell refuses the whole page, and names itself. Activities are out of 3; end-of-term marks are out of 80 or 100 depending on the mode. What you typed is still on screen — correct the named cell and save again.
Whoever installed GradeFlex needs to set the public address before cards are printed, or the codes point at the server itself. Tell us and we will fix it — then reprint.
Ask a person. A confusing screen is something we would rather hear about than have you work around.
