Have you seen an error that looks like this in the Cascade Workspace when trying to preview your page?

Open

The new theme makes use of several cascade velocity formats and blocks to function effectively. One of the most important blocks is referred to as the “calling-page” block. This block is an index block and works to create a dynamic list of your site assets in the form of XML data.

There are two important clues in this message, the details about where the error occurred and then details about the exception. In the example below, the program-hero region is missing the calling block.
