Dear Leslye,
– Regarding the Twitter widget: please try downloading this archive, unzipping it, and uploading the resulting folder into the following directory:
/wp-content/plugins/
replacing any existing files. Then go to “Appearance -> Widgets” and apply the Twitter widget to the sidebar of your choice. The new version of the widget should ask you to create several tokens and keys using the Twitter API.
– The URL of the development website that you’ve provided does not work – could you please double-check?
– Which URL do you have in mind in your last question?
Sincerely,
Andrew / Satori Studio
