I use WP Engine and the filters aren't working correctly
If you are hosting your website on WP Engine and using WooCommerce Product Filters, then you may encounter an issue with indexing and filtering.
If you experience problems with the indexer not indexing all your products, or filters not working correctly (e.g. nothing changes when you apply a filter), then we recommend disabling the WP Engine Query Governor.
To do this, add the following define to your wp-config.php
file (or ask WP Engine Support to do it for you):
define( 'WPE_GOVERNOR', false );
This will disable the governor and allow our queries to work correctly.
