It does not work vote

[Wlad]

Hi!
I changed my hosting provider, has moved into a virtual dedicated server, then in the voting stopped counting votes. Everything works as usual, you can vote, but votes will not be added. I press the button to vote, but the number of votes does not change.

Help please

PS I apologize for my English, I use a translator.

Thanks

My problem with voting:

120765

I tried to install a backup forum in /forum/test_forum/ - everything works, but in the main forum (/forum/) does not work vote.

Can anyone help?
