Good day,
I am upgrading from Moodle 2.1 to 2.2. Before upgrading to 2.2, I delete the Questionnaire plugin from Site Admin -> Plug-ins -> Plug-In overview and also the questionnaire folder in mod folder. I upgrade to 2.2 then add back the questionnaire folder for version 2.2 and install from the Notifications link in Moodle.
The problem is that all my exisitng questionnaires and the responses are gone. I checked the table mdl_questionnaire and it is also empty.
Can you advise how I can upgrade from 2.1 to 2.2 and keep all my questionnaires and responses?
Thanks
