 * Hello!
 * Im trying to import a file and at the last step it get stuck on “Your Import 
   Is In Progress”.
    When i check the console it give me the error: Failed to load
   resource: the server responded with a status of 500 (Internal Server Error) /
   wp-admin/admin-ajax.php
 * I followed the install guides on the wiki and I can’t find anything that I have
   done wrong. Any clue what has happened?
 * Regards,
    Sandra

 * Please update to latest version 3.6.73 and let us know the issue still exists.

 * I’m also seeing this error (most recent version of the plugin).
 * From what I can tell the plugin does a POST when I click Import Now, responds
   with some HTML, a 500 internal server error, and an object (which contains the
   500 internal server error).
 * My PHP settings all seem fine — I thought maybe max_input_vars was the problem,
   but it’s well above. If anyone has a fix for this please share.
 * Thanks,
 * Tim

 * Turns out the problem for me was the featured_image column. It’s a valid URL 
   in the uploads folder, but for whatever reason it was causing the 500 internal
   server error.

 * Ensure that the image is fetch able via browser and also check any htaccess restriction
   exists.
