Hi. I just updated a downloadable PDF resume that I had stored on DropBox and linked to my site. The new file appears correctly and downloads fine in Chrome. However, on Safari and Firefox, I get a 404 file not found error page. Viewing the source code shows that Chrome has the updated Dropbox link, while Safari and Firefox source code shows the old link from the removed old file. I have cleared all fo the old cache from all 3 browsers. Can anyone explain why 2 of 3 browsers would have the old link? Any way to trouble shoot this?
