The demo site has a bug in the latest articles module which is missing out structured data as can be seen on the url below.
Each article in the latest articles module is displaying errors and warnings in the structured data testing tool.
Can this please be investigated as this affects all article modules in this template.
I've reported to the team for further updating on this, thanks for your report.
@saguaros, is there any update to this please? its now 12 months.
This was fixed long time ago, are you using latest version of this template?
