ok, so here it is the deal. i noticed that all people who have problems with the poll dont have installed v228. what you just took out was the forums permissions for the poll. is not a really big deal, but is more secure with it. since you dont have v228 installed, it will not work properly so i recommend you to let it the way it is until you upgrade.
also, you have this line like that in the poll query?
Code:
SELECT thread.*,poll.*
if you dont, put it back and let me know, it should work fine.
