Chat

After my students in one group do a chat session class ends.

Then later I go to the chat.
I click View past Class Discussions
I select the visible group that I want.
I get the error No messages yet


My course settings for groups is visible, force groups.

more notes:
Later period 2 started and ended.
I click View past Class Discussions
I select the visible group that I want.
I get the error No messages yet

I went to the admin page of my moodle site.
I went to logs, under the logs I opened one of the reports again.
I was able to see the chat discussion for period 2.

Chat works. There is just a bug with my web browser or moodle has some small bug. Perhaps the bug workaround is to create a chat. Chat with yourself, logout and then when the real class comes in moodle is ready to save the session. ??
