I had version 2007073101, as you stated in your post.
I tried to go back to that version, but it does not allow me to do so.

Must I do a restore from the old version dump in another moodle instalation and backup each feedback in each course, followed by a restore in the production moodle server?

If so, can I delete the old version and install the newest one available for download or must I use 2007073101?

Thank you so much
