Mary,

Yes, they are very similar. I added a note to https://tracker.moodle.org/browse/MDL-52838.

Hi all

I have set up a pretty conventional workshop. It progressed in to Assessment phase. Once a participant tries to assess another, Moodle throws "Undefined variable: type in moodle/lib/pear/HTML/QuickForm/group.php on line 277" Interestingly three times - for the three missing boxes(?). See screen-shots.

Moodle 2.7.19 (Build: 20170313)
LAMP, PHP Version 5.6.30-0+deb8u1, MySQL 5.5.54
(The same installation as in "Creating a new wiki throws error/moodle/invalidcoursemodule" https://moodle.org/mod/forum/discuss.php?d=350178. Yes, I cleared the caches!)

Hallo Peter

Danke fuer das Testen ein zweites Mal!

Also, ob index.html die Hauptdatei ist oder multiscreen.html, da besteht kein grundsaetzlicher Unterschied.

Die Tipps ueber die Videoformate und Captivate Versionen habe ich weitergeleitet.

Mir ging es darum, ob "Datei" die richtige Weg ist solche Lernsequenzen ueber Moodle anzubieten. Die Antwort ist Ja, verstehe ich.

Aus meiner Sicht ist die Frage beantwortet, dank deinem Beitrag!

Hi

This is incredible! Clearing the browser cache didn't help at first. I had three browsers open, as student, teacher and admin. I cleared the first two. Then thought of the server cache and emptied that too (from the third browser). I can't say which one was right, whatever the problem is gone!

Many thanks! You saved hours of my time, ...

When trying to create a new wiki, I get the following error:
===
error/moodle/invalidcoursemodule
The ID for the course module is invalid. Please contact the site admin.

Debug info: SELECT id,course FROM {course_modules} WHERE id IS NULL

Error code: invalidcoursemodule

It had been working the last time tested, a couple of weeks ago. In between there was only the security update on the 19th.

This is reproducible. No new wiki is possible. Has this been reported?

Edit: Panik! Even existing wikis can not be opened in the whole site. Always the same error!
:-(

Edit 2: Another suspicion is that it started after deleting a wiki which had sub-pages. A known problem?
