I searched the forums and the codex, and was a little worried. This problem must be so basic that I'm an idiot for not being able to fix it.
The problem is that everyone who tries to leave a comment on my blog (mochasteak.com), after they fill in their details, write the comment, and hit 'submit', are all given the same error: "Must be logged in to leave a comment"
The weird thing is that *I* can leave a comment no problem in both FF and IE.
I removed all restrictions from commenting so that not even leaving an email address was mandatory, but it didn't help.
I am running 220.127.116.11 with no plugins.
I know there must be some simple reason for this, but I can't figure it out. Can anyone help? Thanks.
