Cookies do not appear to be enabled on your browser client. You will not be able to install the application with this feature disabled. Alternatively, there could also be a problem with the server's session.save_path. If this is the case, please consult your hosting provider if you don't know how to check or fix this yourself.
However, my cookies work fine. I googled the error and found out the server hasn't set a session save path. It also said I could override it by modifying .htaccess in my root directory.
So I added this:
php_value session.save_path /libraries/joomla/session/storage/server_sessions/
The only problem is that it immediately gave me an access violation 500.
Are you saying you don't support cookies, so I can't install things like wikis, blogs, and content management programs? What's the point of having php and mysql if you can't use these things?
