'Error (404) We can't find the page you're looking for. '
When I try to assess some links that are written in a pdf file by copying & pasting the letters and entering, I see the following message by Dropbox. 'Error (404) We can't find the page you're looking for. ' At the first day when I clicked the links, it worked well. However it hasn't been working afterwards until now. The internet connection of my laptop computer is totally fine and it's exactly the same environment with the first day. I also tried with my mobile phone, but it only shows the same error message above.
