 * I’m trying to backup two WordPress sites. I get this error:
 * “This session has expired. Please return to the app to try again.”
 * and this error when I try again:
 * “There was an error authorizing the plugin with your Dropbox account. Please 
   try again.”
 * Any ideas?

 * Are you clicking authorise, then logging into Dropbox to allow the app before
   clicking continue?

 * Yes I am. I get the first error on the dropbox site. The second error is from
   the plugin.

 * The session expired error happens when you use an old oAuth token.
 * Do you get the same error if you delete and re-install the plugin?

 * Thank you, that solved it.
 * However, now I have a new problem. The backup doesn’t start when I click “Start
   Backup”. It just says “You have not run a backup yet. When you do you will see
   a log of it here.”
 * Scheduled posts do _not_ work. Is this a problem with my web host? WPB2D worked
   fine on my other site install…

 * Nevermind, this seems to be an issue with W3 Total Cache preventing scheduled
   posts, and WPB2D from backing up. Any caching plugin, apparently.
 * I solved it by disabling Object Caching (Database caching apparently prevents
   it too)
