Each CMS page in In-Portal have (among any other things):
- associated design - defines the layout of the page with placeholders with user provided content
- content blocks - content that is used in above mentioned place holders
Pages can be created in 2 ways:
- from scratch - using "New Section" toolbar button of "Website & Content > Structure & Data" section
- from existing pages - using "Copy" and "Paste" toolbar buttons of "Website & Content > Structure & Data" section
The pages created using later method will be missing all content, that goes into content placeholders (content blocks) provided by design.
Solution
In the unit config of "content" unit replace "JOIN" with "LEFT JOIN" in the "ListSQLs" unit config option.
