Thanks for the reply, I did that already, on wp_posts
Still no help
looking at: http://wiki.wordpress.org/?pagename=Error28
then the forum links it has at the bottom:
http://wordpress.org/support/3/1738
http://wordpress.org/support/3/2923
http://wordpress.org/support/3/2760
They all lead to topics saying it was fixed when an issue with space was fixed.
As far as I can tell I am not out of space on my host, but I don't know if I have some SQL allotment that I don't know about...
