Eureka! I got it to work. I just reinstalled the lastest version with a new data base and like a miracle it works! However, I still get the message: "Sorry, site is unavailable now, please try again later."
when I try to put up a new posting in a group.
Also, when I click the "all polls" button I keep getting "no polls available" message, when indeed I have put up a test poll.
Thanks
