Hello,
I'm trying to upgrade from Civi 4.2.1 to 4.2.9 but get an error 404 midway thru the installer (debugging errors copied below). I'm downloading the site to try and do this offline in case it's just the server being too slow, but in the meantime wondered if it was something else or anyone had any ideas?
Thanks
Nic
