 * Hello!
 * I have the site in the wp-engine hosting. Wp-engine using cache system.
 * When I try to add webhook in the facebook developers area, I get an error.
 * “Response does not match challenge, expected value=”1565394482″, received=”\n\
   u003C!DOCTYPE html>\n\u003Cht…”
 * I think it’s maybe the cache issue because when I testing it in the staging version
   it’s working well. (staging site haven’t cache system)
 * Can u help me? I created a support ticket in the wp-engine, but they said what
   I need send them cookie name for excluding from cache system.
 * Which cookie uses the plugins?
 * Thank you!

 * Have the same issue and also hosting on WP Engine. The weird thing is that the
   checkout page where it’s displayed, should not be cached.

 * I personally switched to Pressidium who have MUCH better customer support and
   hosting. All works fine now.
