problem with mediawiki cookies

Question

anytime a user logs into our Wiki they get the following error: "This Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again." Even though the error displays, the user is actually logged in and can make edits as normal. If the user doesn't look closely they can't tell they are logged in and it's causing confusion I would be glad if anyone gives me a hint

Answer 1

I would "check to make sure PHP's directory for storing session data is writable. This directory can be found in the php.ini file under the session.save_path setting. Errors in this php.ini setting can also cause other problems...(and) Make sure the Internet Guest Account (eg. IUSR_FOOBAR, nobody, or apache) has write permissions to the folder listed in the "session.save_path" variable of the php.ini file."
