After installing the latest version of this plugin my IndieAuth plugin stops working. I get the following response from Quill for example:
The token endpoint did not return an access token. The access_token parameter is the token the client will use to make requests to the Micropub endpoint.
The token endpoint did not return a “me” parameter. The me parameter lets this client know what user the token is for.
The token endpoint did not return a “scope” parameter. The scope parameter lets this client know what permission the token represents.
Notice: Undefined index: items in /home/stephenp/public_html/wp-includes/rest-api/endpoints/class-wp-rest-settings-controller.php on line 328
This only happens with Syndication Links 4.0 and above. The previous 3.4 version works.
