Could anyone help us please about how collapsed topic tree can be implemented in Moodle 2.1. It has been installed but is not working.
When we choose it in the settings "[plugin name]" displays in place of the Topics Tree format (Picture is attached).
After it is set, I cannot even access the course correctly; it shows an error on the top of the page (Picture is attached):
"insert_record() not available anymore"
And I am not able to navigate back to the adminitration block to unset it.
I wonder if anybody else has seen that error before.
Thank you.
