Site Health Status of my WP website shows REST API and Loopback request error.
The problem only exist when currency plugins for WooCommerce are enabled.
When following plugins are enabled I get those errors. (I have tried it with both of them)
If the plugins are disabled, the errors will disappear too.
- Currency Switcher for WooCommerce
- WOOCS - WooCommerce Currency Switcher
