Apologies to all our regular contributors as the Blog Heralds comments seem to be down at the moment, after updating MT Blacklist, MT started giving 500 Internal server error messages for posts, reloads and comments. All things being equal should be fixed soon. Can still post new content though at this stage.
UPDATE: after much hair pulling the comments and site are back to normal, except that we have removed the displayed RSS feeds from the right nav bar. There appears to be some clash between MT Blacklist and MT RSS Feed. Not sure what or how, put leaving it as is for now.
