Some time again after April 2011, the comments on my website stopped working.
There are 2 comments on my site, however you can't view them or post new comments. Website is http://www.thexero.co.uk
Theme hasn't changed.
I disabled and deleted all of the plugins I had active on the site, still broke.
Comments are enabled globally.
Comments are enabled on individual posts.
I have run an analyze, repair, optimize on all database tables, yet comments are still not working.
After playing with it all day, I uploaded an image, which comments are working on fine :S
