download stopped working

I’m amazed nobody else has this problem. Perhaps I’ve set it up wrong although it worked fine until a recent update of plugins. I use file-Manager to add a file. I assign a password. I update the package. I then go to download page and alter the reference there to refer to that package for download. I press ‘update’ for that page. all looks good but no password is acceptable when you try to download. Works fine if I drop the password. Seems I have standard basic setup but maybe I’ve selected English-Ireland keyboard or something like that makes me an unusual case causing a failure. Seems like the final ‘return’ when I enter the password is not being received.
