ERROR: Dropbox API: (500) Internal Server Error

I am having the exact same problem, was working fine and now I get the Dropbox API: (500) Internal Server Error

Did you guys found the cause ? I′m also having this problem

Sorry, but the “(500) Internal Server Error” cames from the Dropbox servers. Best thing to do is be patient and give it another try.

Heya,
Am having same issue, but only from some sites and not others. If DB prob any idea why not on all sites?
thnx!

Yes indeed, problem went away after a while, just had to wait it out ??
