Some people IPO addresses adding comments (whether as a new comment or a reply to an old one) makes the screen go blank, on some posts. Not on all posts. One post it is occurring on is http://www.dogsdontlookbothways.com/joeys_blog/2999-dog-hit-by-car-broken-jaw-leg-pelvis/
It happens mostly with posts that have a lot of comments, though I have turned off the "break comments into pages" and I have nested comments set to max of 10. It happens with a new comment that does not have a parent.
I've optimized and repaired my database.
So what's up?
I'm using "Suffusion" theme.
Thanks.
