I've reinstalled the latest version on my site. I deleted all of the old files apart from the database. I ran update.php and that worked fine.
Come to log in, and it simply will not let me log in - says that user name is invalid and cookies are disabled. Cookies are enablend and I've tried to log in with IE and FF. The user name is the same as the name in wp-config, and that is the same as the use name set up in the database in MySQLserver.
Any ideas please? Thanks
