The errors/.mlist/ contains many empty files - I guess that’s because Anonymous Coward's posts have no content. The error_log tells us

So why is FUDforum failing to parse my messages? As I said, I had a working version yesterday...
None of the files in .mlist appear to contain messages sent to FUD from email, which I would expect if the mailist.php script was running correctly. As far as I can see there are only blank messages which would suggest they are from Anonymous Coward.
