This is how you configure WP Engine to work with WishList Member for Infusionsoft.

When installing on WP Engine, you will need to contact WP Engine support and request that they turn off the “redirect_bots” setting, and purge the cache.

If this setting is not disabled, then it will not be possible to send HTTP POSTs to your app, as the WP Engine server will intercept and stop them from succeeding.

You’ll need to send a support ticket to WP Engine Support and ask them to allow your posts to contain variables.

Here is a sample ticket you can send to them…

Hi,

We’re using Infusionsoft and we need to send an HTTP Post to our WordPress membership site to set a password. The HTTP Posts that are being sent to WPEngine return an Unexpected 301 result if you have a query string added to your post URL.

For instance this will fail: http://site.com/?operation=makepass
But this will work: http://site.com/

Can you please modify our nginx configuration for this install to allow variables on our HTTP Posts? And can you turn the “redirect_bots” setting off on my hosting account?

Infusionsoft’s IP Range is 208.76.24.0 through 208.76.24.22

Thank You!
