 * Hi,
 * all new 4.x versions of the plugin are causing http 500 script errors when submitting
   a blog post. I enabled debugging in wp-config.php though there is nothing related
   to it in there.
 * Version 3.5.5 is working fine without any problems.
 * Any idea what might be causing the script errors?
 * Thanks,
 * Dave

 * 3.x used to give same error in wp-ajax while submitting when I had to reconnect
   with my credentials appid and appsecret because the token has expired (very annoying
   thing by the way)
