Hello, I also have this problem of a “blank” site, even though the admin site/dashboard works. It is also caused by the:
`Call to undefined function: wp_remote_request()
in my error_log. However, none of the suggestions works:
1. I copied everything native on the server from a tar.gz, so no FTP involved
2. I disabled all my plugins, and even switched back to the (new version of) default theme, but it still doesn’t work.
3. I don’t see any “Automatic Upgrade” plugin, so not sure what MONKMASTER is referring to.
So, sadly, downgrading to WP 2.6.5 from my backup until this issue has been further debugged.
