Structured data may not get generated on your site, and you wonder what the problem is. The following are some common causes of this problem.
Ensure the Google Structured Data system plugin is activated
Go to Extensions -> Manage, search for "System - Google Structured Data" and make sure the plugin appears in the list and it is activated.
The structured data item is unpublished
Go to Google Structured Data -> Items and make sure the item is published.
The structured data item is assigned to the wrong pages
Go to Google Structured Data -> Items, click to edit your Item, and make sure you assigned the item to the correct pages using the Publishing Rules section.
You're checking the wrong page
Make sure you're checking the correct marked-up page. Remember, our extension supports marking up only the detailed page of the component. The Category/List/Blog views are not supported.
The cache is not cleared
If you're using a cache mechanism, clear it and try again.
Deactivate potential conflicting plugins
To limit any potential conflicts with other plugins, temporarily deactivate other potential conflicting plugins one by one. It is recommended to deactivate security, firewall, optimization (JCH Optimize), and caching plugins (Page Cache). You can reactivate the plugins after you’ve successfully solved your issue.
