 * Hi [@amawoqueen](https://wordpress.org/support/users/amawoqueen/)
 * I can see that your website is loading correctly, and that the Jetpack connection
   is solid there while you are using both the Jetpack plugin, and the Jetpack Boost
   plugin.
 * Do you still see that error? If you do, please share with us where it’s appearing
   specifically.
 * Best,
