Some of my regular commenters are telling me they are getting a "User Must be Registered and Logged in to Comment" message on my blog. In Settings: Discussion, that box is NOT checked as a requirement for commenting, so unchecking it will not help them be able to comment.
Even worse, when they try to log in, they cannot. They just get placed in a circle of trying and failing. This is happening to more than one commenter.
This problem started cropping up in the past few days, though I have done nothing to change my discussion settings. Is there some other issue with WordPress, or some other place I can go in my settings to resolve this issue? I have many loyal, regular commenters who will stop trying if I can't fix this for them.
Thank you for your help.
The blog I need help with is andrawatkins.com.
