This tutorial features the Feast Plugin, which contains theme enhancements.
Certain WordPress hosting/installation setups have filters enabled that rewrites emoji characters to externally hosted images. This is a poor setup because:
- it causes an external DNS lookup, slowing pagespeed
- it causes images to be downloaded from an external server, slowing pagespeed
- it adds DOM nodes to the page, slowing pagespeed
- it leaks visitor information to the external host (s.w.org), leaking customer data and causing tracking concerns
- rewriting UTF8 text-based characters to images breaks the Advanced Jump to Links
Because of the above, we believe that no website should be using this feature, and as such, we've decided to automatically disable it.
As of the Feast Plugin 5.0.0, this is automatically disabled.
While we don't recommend it, you can re-enable this by disabling the Feast Plugin's setting using the following code in the Code Snippets plugin:
add_filter( 'enable_feast_plugin_emoji_rewrites_disabled', '__return_false' );
