I used to be able to upload files to my Dropbox account by clicking Upload, clicking the file I want uploaded and then click the Open box. Now when I do all that, the open box is faded and won't let me click the button. This is on Google Chrome. I also tried it on Microsoft Edge and the same thing happened, but it does have an "Upload from Mobile" button that doesn't do anything. I have a free basic Dropbox account, and I am only using a quarter of my 2 MBs of storage space. Please help me with any suggestions. Thanks!
