If you are experiencing unfamiliar hiccups with the system and simple features like editing that worked before:

1. Click the menu icon in the top-right corner of your Chrome window and click Settings.

2. Click Security and Privacy in the left navigation menu.

3. Click on Cookies and other site Data

4. Toggle on the setting for "Allow all cookies"

Scroll down from there and and review the list of blocked sites under the section "Sites that can never use cookies"

Make sure that mailbox power, mediaclip, mediacliphub are NOT in that list of blocked sites.

After the changes are made close all browser tabs and the browser.

Re-Open Chrome and try to load the project again.
