Most means anything that could mess with the URL, I did not turn off jetpack and sitemaps plugins.
{edit} I’m also confused by the URL being messed up. I know you both are referring to this, but I don’t see it. Just looked at the page source again and I can’t see anything wrong with the URL. Where do you see this?
Tonight, I can PM you ftp + wordpress access and turn off plugins, plus activate wp default theme. Does that work?
