Progress bar and redirect not working

Uploading to dropbox works fine, but I can’t get the progress bar or redirection after upload to work. I can set the thank you message and it works, but I’d prefer a page redirection.

I have “Show upload progress indicators” set on True, also “Page directed to after uploading a file” is selected correctly. The settings are correctly saved in the database too.

Interesting thing is, the progress bar worked fine yesterday but not anymore. I’ve tried this with both Chrome and IE.

Any ideas?
