ERROR: Dropbox API: (401) Token is disabled or invalid

no idea, but I too have just upgraded to 3.0.4 and I get the dropbox error the same as you.

Just wondering:

Were you using the plugin to backup multiple sites or just one?
Were you using Sandbox or Full access mode?

I’ve tried both sandbox and full access. I have mutiple sites on the same server (15+). I think I’m using WP Backup on 3 live sites and two staging sites

I’m using a different drop box account for each site (live and staging count as 1 site)

I’ve also tried Full Access and it doesn’t work.

I wonder if anyone else had the same problem and found a solution?

same problem for me!!!!!!!! help!!!

Anyone found a solution yet? There is a post on the “Pro” forum talking about the same issue, but the suggestion was to simply re-authenticate with Dropbox. I have done this many times already and it doesn’t not work but I will try it again test the result.

For those who have similar problems, I have just authenticated with Full Access and it now works for me.

FWIW I did it on a separate computer though I doubt it should make a difference. Hope you guys fix your issues.

Re-authenticated, to be clear.
