I've just installed WordPress 3.2 and am trying to do the automatic update to version 3.3. This is the error message I get:
Downloading update from http://wordpress.org/wordpress-3.3.zip…
Unpacking the update…
Warning: copy(/homepages/37/d396920207/htdocs/app396920223/wp-admin/includes/update-core.php) [function.copy]: failed to open stream: Permission denied in /homepages/37/d396920207/htdocs/app396920223/wp-admin/includes/class-wp-filesystem-direct.php on line 200
Could not copy files.
I would appreciate any advice on what this means and how I can fix it!
