Sometimes, the Due Date Modifier and Template Builder do not show any course assignments or template names. This is because the API token is missing from the course. To force a new API token, open the Module Builder.
Due Date Modifier
If the content in the Due Date Modifier is missing titles and clicking on the existing content gives a 404 Error: Page Not Found, the Multi-Tool needs to force a new API token by going into the Module Builder.
Template Builder
Likewise, if the Existing Templates are missing titles and clicking on the existing gives a 404 Error: Page Not Found, the Multi-Tool needs to force a new API token by going into the Module Builder.
Force a New API Token
To fix this, open the Module Builder within the Multi-Tool. This will force a new API token to be generated.
