I've noticed that the automatic plugin updates are no longer working, though they have been in the past and I haven't made any config changes to the website. I get an errors message like this:
Downloading update from http://downloads.wordpress.org/plugin/share-this.zip
Unpacking the update
Could not copy file: /homepages/45/d171125682/htdocs/stevedalenet/wp-content/upgrade/sharethis/share-this/screenshot-1.gif
Can anyone offer any advice on what to do to resolve?
