Advance poll suddenly don't work.

I've set up advance poll some times ago. For the past few weeks the vote is stuck at 71. Im thinking why suddenly no one seems interested to vote. Then I tried to vote once to check wheter it works and I got this error.

Here's my site. http://otsuka-ai.jp Please help. Thanks in advance

I'm guessing you are using the text version. It looks like the write permission to the data files has been changed. I believe they should be 777.

Thanks for the help

I also can no longer even take a poll (using database). I can view the polls with php code but when I try to take a poll it merely returns to the poll without showing results. I also get ignored when I try to log into the admin window without error.

I'm hosting on Mac OSX and it worked fine but just suddenly stopped and I wonder if it was because of a security update from Apple (I can't remember the sequence). Anyone else having a problem recently?

Do I have my permissions screwed up?

Thanks for any help.
