Thanks for the quick response and ideas, @jeffstieler.

TL;DR: I had only one moment of success but was short lived and I couldn’t replicate that success again. It was related to the “Jetpack by WordPress.com” plugin and WordPress.com user account token connection to that plugin.

Apologies in advance for length of this reply but it might be useful and/or save others the pain of going through the same process.

When checking Firebug, I saw this error in the console:

"NetworkError: 400 Bad Request - https://mydomain.com/wp-json/wc/v1/connect/services/usps/5"

I set both WP_DEBUG and FORCE_SSL_ADMIN to both “true” and “false” and alternating values with the same result.

I switched themes to “Twenty Seventeen” with the same result.

I turned off plugins one-by-one until I got to “Jetpack by WordPress.com,” which gave me a surprising and welcomed error message, after I reactivated it and reconnected my WordPress.com account:

“There was a problem with one or more entries. Please fix the errors below and try saving again.”

Unfortunately, I did not capture the JSON put in this success scenario and the happy editing of the form didn’t last long. In less than a couple minutes, another error message indicated that I wasn’t connected to Jetpack, when the plugin seemed to indicate that I still was:

“Unable to send request to WooCommerce Services server. Jetpack Token is missing”

Thinking that I could simply disconnect and then reconnect my WordPress.com account without deactivating/reactivating Jetpack didn’t go over well. I was met with this error:

“Invalid request, please go back and try again.
Error Code: invalid_client
Error Message: Unknown client_id.”

Even after clearing my cookies, the error message came up again. It wasn’t until I actually deactivated/reactivated Jetpack that I was finally able to reconnect to my WordPress.com account.

After all that, I saw this again in the shipping zones form, when I tried to submit changes:

{"code":"bad_form_data","message":"Unable to update service settings. The form data could not be read.","data":{"status":400}}
