I do not even know how stupid is my question so please help me out; it's not working: whenever I try, it adds one field, but when I try to insert more, instead of inserting the new one, it removes the earlier one.

And yea can someone please advise me how can I change/downgrade my database from version 5 to version 4 of mysql? I want to install debaser which is not installable under the current settings but at the same time I do not want to lose any of the user base.
