Hi, I can´t select pictures for slide images any more. When I click the "UPLOAD" button, there should open the select nothing happens (javascript:void(0); The browser error console gives me a 404. Also on entering the path directly in the browser I get 404. I entered FTP and the file is there. I also can´t see my pictures any more when I enter the media center. The site workes as usual. (plugins tested, Salient up to date, multisite network, strato hosting)

Thanks for helping! Robert
