Just had an email from a lovely person telling me that she couldn't comment on my blog posts anymore, and that there was a message saying that you had to be a member to post! I thought this sounded a bit odd, but went into my settings and, lo and behold, the "members only" checkbox was ticked in the comments section.
I sure as heck didn't tick it, so who did?!
Anyway, reader comments are now enabled again. Thank you to the lovely Lucy for letting me know - goodness knows how long it would have taken me to find out otherwise!
Anyone else had this problem?
