How to fix: unable to view any Quotes

[Viktor]

Question:

Quotes can't be opened in Zuora Quotes, error message is "URL No Longer Exists" or "The webpage at XXX might be temporarily down or it may have moved permanently to a new web address.", how do I fix this?

Answer:

Please disable Clickjack Protection for your Visualforce pages.

Salesforce has introduced Clickjack Protection that can be enabled on Salesforce Orgs. However since Salesforce is rendering the Zuora Quote screens as frames, and Clickjack Protection affects all frames and iframes, enabling this setting will prevent you from displaying any frames.
