I did a poll import as part of a conversion from IPB 3.2 to XF1.1. The converted site has been running a few days and we've discovered all the poll information is wrong. Who voted for what is totally out, and poll results do not match what was previously recorded. What I would like to do is remove any existence of current polls, so that we can start again. I am assuming this will be a mysql query to empty the tables. Could anyone specify the exact details of what needs to be done please?
