[Plugin: WordPress Automatic Update] Cannot update other plugins automatically

Hi there,

After using the WordPress Automatic Update plugin to update to 2.6, I have discovered that I can no longer use the built-in automatic update feature of WordPress to update other plugins.

For example, a new version of All-in-one SEO is available, so I click to update it manually and enter my FTP credentials. It starts to run and then provides the following error:

Downloading update from http://downloads.wordpress.org/plugin/all-in-one-seo-pack.zip

Unpacking the update

Could not create directory: /public_html/public_html/wp-content/upgrade/all_in_one_seo_pack/all-in-one-seo-pack/

Installation Failed

Somewhere along the line something has changed the directory of plugins to /public_html/public_html and I can’t seem to find out where!

Any help would be great.
