 * Everything seems to be running okay until it tries to upload the zip to Dropbox.
   I’m hoping this is an easy fix as I am close to settling on the premium version
   of this plugin as my backup solution for all of my sites.
 * Thanks for your help!

 * Hi yardle,
 * that error seems to be on your server only. Please check if you have SSL for 
   php activated (ask your web hosting provider). And check if your web host supports
   ssl on the serverside. Maybe they do not support SSL and our plugin can not get
   an encrypted trusted connection with dropbox. Please ask your web host provider
   these questions.
 * regards,
    Robert

 * Hi Robert,
 * Thank you for the reply.
 * Does this mean I have to purchase an SSL certificate from my host for the plugin
   to work?
 * I’m currently trying to run the plugin on a GoDaddy shared hosting plan. The 
   plugin seems to authenticate with Dropbox just fine, it just won’t upload the.
   zip file.
 * Thank you for your help.
 * James

 * Hi yardle,
 * no you don’t need to buy a certificate. Your Server should allow trusted connections.
   To check this error please change the following in the file inc/class-destination-
   dropbox.php
 *     ```
       curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, TRUE );
       curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 2 );
       ```
   
 * into:
 *     ```
       curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
       curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 0 );
       ```
   
 * This will disable the SSL certificate check.
 * regards,
    Robert
