I am seeing this as well. When I go to the Media section of the Dashboard and regenerate an image one by one, it appears to work.

Looks like you might be getting a PHP error.

What happens when you visit this URL?

yoursite.com/wp-json/wp/v2/media?page=1&per_page=25&_fields=id&is_regeneratable=1&exclude_site_icons=1&orderby=id&order=asc

Hope it will be usefull.
My function.php contains next lines
```
remove_action( 'init',          'rest_api_init' ) // remove this line;
remove_action( 'rest_api_init', 'rest_api_default_filters', 10, 1 );
remove_action( 'parse_request', 'rest_api_loaded' ) // remove this line;
```
After i commented the 1st and 3rd lines the error “Unable to fetch a list…” was solved

Yeah, my plugin as well as WordPress itself uses the REST API. You should not completely disable it.

If you wish to restrict access to the REST API, then use the rest_authentication_errors filter to restrict it to logged in users:

Sorry for the late reply.

I updated to 3.0.1, same error.

I tried your link mentioned aboved and got a error from my self written theme and plugin.

Changed

if(is_plugin_active("blabla"))

to

if(function_exists("is_plugin_active") && is_plugin_active("blabla"))

Now your plugin works. It was not your fault, it was mine. 🙁

Your link again presents a correct result.

I did the changes in my self written plugin and theme of course.
