I can't start the Dropbox app

[loftybecker]

Dropbox couldn't start and put up a box saying "Please contact Dropbox support with the following info," which is apparently an error log. But how do I contact them?

Hi @loftybecker, thanks for joining the Community!

You can see all your support options on this page when you login to your account.

This way I can see what is causing the issue.

Hi @loftybecker,

Try following in terminal (line by line):

sudo chflags -R noschg ~/Dropbox
sudo chflags -R nouchg ~/Dropbox
sudo chown -R "$USER" ~/Dropbox
chmod -RN ~/Dropbox
chmod -R u+rw ~/Dropbox

What is the result? 🤔

Hope this helps.

Did the job, thanks!
