DropBox & BackWPup weren't communicating well (error messages!) so I updated the plugin to v3.1.1 and it was able to backup to DropBox again. Then I updated WordPress to 3.8, and now I'm getting "ERROR: Dropbox API: (403) Unable to parse OAuth parameters from Authorization header."
It looks like DropBox & BackWPup are back to not being able to communicate.
Anything I can do to help?
Thanks in advance...
