Are you using v8.1.0 or have you updated to v8.1.1 and broke the nulling?
Update Soledad Version 8.1.1
Feature Added: 5 new great demos:
Please update the theme to the latest version & the plugin “Penci Soledad Demo Importer” to get those demos.
We’ve added those demo templates to our Template Cloud Library – so you can find them inside the Template Cloud Library also. There blocks from those demos will be added to our Template Cloud Library soon.
Improve: We’ve added the cached for critical files for similar posts/pages to make it faster to load when you use our optimised speed modules. We’ve improved the loading time of lazy load images to make them load faster. Please update the plugin “Penci Shortcodes & Performance” to the latest version.
Improve: Some minor issues.
