Thank you for your report, I just did a small fix and release a new version 3.7, just update and changes must be corrected.
Greetings from Costa Rica.

grossmann commentedWow, thank you for your fast reply. I tested the new version (3.8 btw) and the errors are no longer thrown. But I get an green message with "Invalid signature." if I try to upload a file. And the file don't get uploaded. I am running this on drupal 7.17. Could this be a problem?

-enzo- commentedHello Grossmann
Can you upload a picture(s) showing the error?
Comment #4
grossmann commentedI have updated to drupal 7.22 with no difference. Error message which is displayed after pressing upload is attached as image.

Do I need to have an SSL certificate running and reaching the website over https?
Comment #5
-enzo- commentedI never see that error, the error must be caused because DropBox change some stuff recently. I will next review next weekend.
If you can debug and propose a patch the community will be really happy :P
Regards.
