I'm working to install WordPress for a client on 1and1 hosting (which I am not familiar with). I installed WordPress fine in the back office, but when I enter the Dashboard and try to update to the latest version of WordPress, I get this error EVERY TIME:
Downloading update from http://wordpress.org/wordpress-3.4.2.zip…
Unpacking the update…
Warning: copy(/homepages/43/d300409144/htdocs/app438160177/wp-admin/includes/update-core.php) [function.copy]: failed to open stream: Permission denied in /homepages/43/d300409144/htdocs/app438160177/wp-admin/includes/class-wp-filesystem-direct.php on line 200
Could not copy files.
I've never had this problem with any other hosting so PLEASE help if you can :(
