Well, I'm about at the end of my rope.
My understanding was that WordPress v2.3.1 was supposed to solve this error that appeared with v2.3. It has not, for me.
I get three errors when I log into my blog:
* "ERROR: WordPress requires Cookies but your browser does not support them or they are blocked."
* "ERROR: The username field is empty."
* "ERROR: The password field is empty."
They do not prevent me from logging in. I do not have any extra spaces following the ?> at the end of my config file. I am in v2.3.1. I turned off my plugins before upgrading, both with 2.3 and 2.3.1, and turned them on afterwards. I have deleted all cookies related to my WordPress install.
I am using Mac OS X v10.5 and Firefox v22.214.171.124. I do not have a firewall active. My cookies are set to be kept until they expire.
Any help would be sincerely appreciated.
