Creating a custom page for grader report.
Error showing -"Coding error detected, it must be fixed by a programmer: Invalid state passed to moodle_page::set_state. We are in state 0 and state 3 was requested."
Header is loading again.
Any help what can be the possible issue or what the code is missing.
Thanks
Check for an additional $OUTPUT->header() call. This sort of thing can happen if you have more than one.
Check your $PAGE->, require_login(), and $OUTPUT stuff against a report that works.
I have made a custom page where I am calling moodle grade files.
Right... but it still needs to match pages of a similar type.
Attach the code if you like... or point us to it in Github if you use it.
