Problem with Advanced Poll 2

The problem I'm having is the one described in the read me file:

Appears after voting.

I've tried the solution giving in the FAQ but it doesn't work. In fact, the code it says to add:

Seems to be causing the problems. I already have:

That in my page, and adding what the FAQ says to add, does nothing. However, deleting both sections of code takes away the error. The problem then becomes that you can vote multiple times in the same poll. Does anyone have any ideas as to what may be causing this?

tis got to be at the very top of ur file before the html tag or before any output at all. because headers are sent first before otuput so basically u would be trying to go against the rule so it wont work.

Yeah I did that, it still had that error.

Make sure there are no blank lines before or after the code or at the end of the document. Many html and text editors will insert blank lines, which I why I edit files in my ftp program or CPanel's File Manager. Note: An ftp program that does not have its own editor but uses Notepad may also cause this problem.
