WordPress version: 3.4.2
WordPress SEO version: 126.96.36.199
I did this: Clicked update to WordPress SEO 188.8.131.52. via WordPress.
I expected the plugin to: update.
Instead it fails to install (message: Installation unsuccesful).
A following check with an ftp program reveals that the WordPress SEO folder is now empty except but for a CSS folder icon (also empty). All SEO work is gone.
I tried disabling all plugins before updating but it still fails.
What to do? Please? Really looking forward to resolve this.
