If cookies are disabled, it's will each time a page loaded result in that
isset($_SESSION["count_session"]) will be false, and your script will try to
set a new session but it will be ignored by the browser.

You should include a cookie check in your page (this could be done with
javascript and result in an alert if it notice that there hasn't been a cookie
set and tell the user that the site needs cookies to work properly, of course
the user could have disabled the javascript too and this case you can use a
reference check, if it notice that the reference is to your pages and it don't
find a cookie it could generate an error message to the page where telling
about cookies, but references can be turned off too).
