Since the release of BackWPup 3.1.2, I’ve been answering the question of “help, my DropBox is giving me errors”. Here’s the quick solution. This isn’t a new solution (in fact it comes from the plugin author), but a lot of people have complained that the solutions already posted were not simple enough for them to follow the instructions.
Note: Updating to a more recent version of BackWPup also solves this.
BackWPup DropBox API Error
You’ll get an error something like:
Dropbox API: (59) Unknown cipher in list: ECDHE-RSA-AES256-GCM-SHA384...

This is an issue affecting version 3.1.2. Basically the issue is that DropBox and BackWPup stopped playing nicely with each other. The good news is that the developer knows about the issue and will be including a resolution in the next update of BackWPup. The bad news is we don’t know when that update will be.
While you are waiting for the next version of the plugin to be released, there is a temporary fix and it’s been blessed by the plugin author.
The solution is what’s called a mini-plugin, and I’ll walk you through the steps for how to install it:
Step 1: Download Mini Plugin to Your Computer
You’ll need to download the mini plugin to your computer. One thing to be aware of though, the plugin must stay as a .zip file. If your browser automatically uncompresses files, you will need to go into your browser preferences and turn that off for the moment.
If the file doesn’t download properly, right-click on the link and then select Save As or Download As (exact wording varies by browser).
Step 2: Manually Install and Activate
From your WordPress dashboard click on Plugins and then Add New.
From the Install Plugins screen click on Upload.
Click on Choose File, select the zip file that you downloaded and then click on Install Now.
You’ll see a message saying that your plugin has been installed successfully. Click on Activate Plugin.
You will be taken to your Plugins page and see that there is a new plugin just below BackWPup. That’s it. Now you can go back to BackWPup and authenticate with Dropbox.
