ERROR: Dropbox API: (59) Unknown cipher in list (followed by a list of errors)
The patch for this can be found on the WordPress.org support site forum. I hope there will be a fix in the next upgrade. Create the following PHP page and add it into your wordpress plugins folder. Copy it to a text editor and save it to your desktop and use Filezilla or another ftp file manager to move the file from your desktop to the WordPress/wp-content/plugins folder. You will then need to go to your WordPress dashboard to activate it as a plugin.
php /** * Plugin Name: BackWPup disable SSL connection verifying * Plugin URI: https://marketpress.com/ * Description: Disables the verifying from SSL connections in backup destinations * Author: Inpsyde GmbH * Author URI: http://inpsyde.com * Version: 0.1 * Network: true * License: GPLv3 * License URI: http://www.gnu.org/licenses/gpl-3.0 */ add_filter( 'backwpup_cacert_bundle', '__return_false' );
This eliminates the need to verify an SSL connection and the files will upload without the unknown cipher error.
