I have a big problem.
I manually updated the WordPress to last versione (3.1.3), but when I go to panel admin, I see that WordPress isn't update.
So I try with automatically update (update-core.php) and i receive this error "Unable to locate WordPress Root directory. Installation failed.".
The folder "wp-content" exists and it has permissions 777.
Moreover, into page "plugins" I don't see plugin, but in the directory /plugins/ there are all. The plugin don't work.
While I try to install a new plugin from panel admin, I receive this error "Cannot find Content directory".
How do I fix?
