If there are sub-folders in the Moodle file area, you have to make sure you upload files into the correct folder. Cure: In the Files window, move the uploaded file into the correct sub-folder. Prevention: If possible, avoid using sub-folders if all the files are in the same folder, this problem cannot occur. If you do need to use sub-folders, take extra care when uploading to put the file in the right place. It helps to replicate the same folder structure in your local version.
