Dear Dr. Richard Lobb,
I am asking this question here (already asked here) because, this "filter_embedquestion" feature is used by you here and there at https://coderunner.org.nz/.
I tried to embed questions on a Moodle course page through TinyMCE Editor (using filter_embedquestion_moodle51_2025091602 and tiny_embedquestion_moodle51_2025091600 on Moodle 5).
If I try to view the quesiton on the course page, I am getting the error "This embedded question is incorrectly configured.".
But the questions from the question bank seem to work good if we open preview from "question bank->preview".
For your information, I followed the procedure explained here.
Sorry if this question is irrelevant to this forum.
