       Hello
       I use your plugin to display a map (fixed background image). and clickable links.
       I have an error message when I activate the module again:
        This extension generated 506 unexpected output characters when enabled. If you notice "headers already sent" messages, issues with your syndication feeds, or other issues, try disabling or removing this plugin.
   
       And since I installed it I have a 504 badgateway timeout
       ```
   
 * Do you have a solution to these problems?
    Thanks Nicolas

 * Hello. As I can see your web page has many warnings about mixed content issue.
   Try to go the WordPress settings and change the HTTP prefix to HTTPS in WordPress
   Address (URL) & Site Address (URL) input fields.
