How this works? I tested password protection and it affects the plugin once activated. * Plugin Author [RevenueHunt](https://wordpress.org/support/users/revenuehunt/) * (@revenuehunt) * [4 years, 4 months ago](https://wordpress.org/support/topic/error-rest-api-5/#post-15290182) * Thanks for letting me know [@outiojala](https://wordpress.org/support/users/outiojala/)! * I believe each password protection plugin might work differently, the one I tried long ago did allow me to work on incognito. * [chapman2022](https://wordpress.org/support/users/chapman2022/) * (@chapman2022) * [4 years, 1 month ago](https://wordpress.org/support/topic/error-rest-api-5/#post-15551320) * Hello, I have made several tests to install the plugin and it always gives me this error. * It seems like there’s something interfering with your WordPress REST API.
