nextgen gallery not working correctly

To whom it may concern, I can't open/edit my galleries/images inside (admin) nextgen gallery in wordpress. I'm have reinstalled the plugin but didn't make a difference. Permissions look good via FTP....and the plugin worked before. FYI I get this when I create a new gallery: Gallery ID 10 successfully created. You can show this gallery in your post or page with the shortcode [nggallery id=10]. Edit gallery The server setting Safe-Mode is on ! If you have problems, please create directory wp-content/gallery/test and the thumbnails directory wp-content/gallery/test/thumbs with permission 777 manually ! I only have access to FTP and the wordpress admin. The work will be done via Teamviewer. This worked before.
