I have had my blog running for about a month, without a single problem (WP2.0). But since today, the comments no longer show up. They exist: they show in the admin pages but not on the blog itself. They are not waiting for moderation.
I did install a second blog, on the same domain, using a different mySQL database, could that have caused the problem? If so, would deleting that second blog do the job?
Thanks for any help.
