  • sorry but where is that plugin ? I have similar problem.

    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:

     * Plugin Name: BackWPup disable SSL connection verifying
     * Plugin URI:
     * Description: Disables the verifying from SSL connections in backup destinations
     * Author: Inpsyde GmbH
     * Author URI:
     * Version: 0.1
     * Network: true
     * License: GPLv3
     * License URI:
    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 🙂


    That’s too complicated for me.

    agreed. I am not a coder.

    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:

    Best regards

    thanks Daniel, it worked only with your provided mini-plugin
