I changed the permissions of the wp-content folder to 777.
I uploaded the xml file by myself in the uploads folder. (I use Filezilla)
I checked again the permission stuff.
I tried again to use the WordPress Importer and again:
Sorry, there has been an error.
The uploaded file could not be moved to /srv/www/vhosts/the_url.de/httpdocs/wordpress/wp-content/uploads.
What should I do?????
thanks for any help....
