 * I was told about your plugin to compress images on our WordPress site. So I added
   the plugin to test on our staging site. This is not cached on Google, so the 
   public can’t view it.
 * I added the plugin, doing what was required to set it up. But it doesn’t compress
   the images. When you click on the option, you get a spinning wheel and that’s
   it.
 * What’s going on. It doens’t look as though I am the only one experiencing the
   issue.
 * Thanks

 * Hi [@isurman](https://wordpress.org/support/users/isurman/)!
 * This is Joseph from Imagify, and I’ll gladly assist you here!
 * I noticed that when I tried to visit your site, it is behind HTTP Authentication.
   For optimization to happen, our servers need to communicate with yours because
   optimization happens on our servers. So you have a couple of options to try:
 * 1) You can whitelist our IP addresses and URL so the username and password are
   not required, which are as follows:
 *  • 149.202.181.71
    • 167.114.243.35 • [https://app.imagify.io](https://app.imagify.io)
 * 2) Adding the following code to your wp-config.php file may allow access as well:
 * define(‘IMAGIFY_AUTH_USER’, ‘your_username_here’);
    define( ‘IMAGIFY_AUTH_PASSWORD’,‘
   your_password_here’ );
 * If neither of these works, then you may need to try disabling the HTTP authentication
   while you are optimizing your images.
 * Please let me know how this works for you, and I am happy to be of further assistance
   if needed!
 * Best regards,
