I'm running 5 WordPress sites. 2 of them refuse to auto-install upgrades, and give the error "Unable to locate WordPress Content directory (wp-content)". For the life of me, I cannot figure out why, and it is frustrating beyond all belief. I also get a similar error when auto-upgrading WordPress plugins. The CHMOD values are the same across all of these sites...so, why does it work for some and not for others?!
