I have a problem. In a customers installation, the administrators are not able to upload files. If you go to any course page, edit it, and add a resource, in the resource page you can see the "Selected files" box. But there's no option to upload files.
On the files box, there's the "drag&drop not supported" message.
If you click the file button, you have different options: content bank, url download, server files, etc... But there's not the "upload file" option.
Have checked file permissions on moodledata folder, and checked plugins options to trying to find some misconfiguration. But can't find nothing.
Can you help me please?
