 * I’m technically illiterate. I don’t have a clue how to install the mini Plugin
   Daniel offered. Is there a simpler way to fix the “unknown cipher” error since
   I updated to 3.1.2? Can I restore 3.1.1? How do I do that? Thanks.

 * In the post entitled “[resolved] 3.1.2 broke Dropbox for me,” Danieloffers a 
   mini plugin, but I can’t figure out how to install it. Here’s the code:
 *     ```
       <?php
       /**
        * Plugin Name: BackWPup disable SSL connection verifying

       add_filter( 'backwpup_cacert_bundle', '__return_false' );
       ```

 * If I’m right, you have two options:
 * 1) create a text file called for example backupminifix.php and copy / paste the
   code in it, save it in your website’s /wp-content/plugins/ folder
    2) open an
   existing functions.php file in your website’s currently used theme folder and
   paste only this part in the end of the file:
 * `add_filter( 'backwpup_cacert_bundle', '__return_false' );`
 * Someone please correct me if I’m wrong, but that’s what I would do 🙂

 * Solution #1 proposed by Kramarz is very easy to implement and is the best way
   to do it.
 * All you need to do is copy the portion of code in an empty text file, save it
   as whatever.php and put it in /wp-content/plugins/ using an FTP client.
 * Then refresh the installed plugins page in WordPress and activate the plugin.

 * I’ve finally managed to upload and activate Daniel’s mini plugin. It took me 
   so long because I had learn what FTP is, what an FTP client is, which FTP client
   to use, and finally how to use it. As I said at the beginning of this thread,
   I was technically illiterate. I guess now I’m technically semi-literate. My thanks
   to Daniel and everyone else who offered help.

 * Thanks guys. Method #1 worked its charm!
 * I just opened my sites Cpanel, and trough my host client (hostgator) i was able
   to go to the correct folder and upload it without using an ftp client.
 * All I then had to do then was to go to my WP’s backend and activate the mini 
   plugin!
 * A great video showing how to do all the rest can be found here: [](http://youtu.be/giiB3vSLYz4)
 * Best regards
