Templates Missing from the Template Library?
If website templates from older legacy plans are missing from the Kit Library, your site may be using the new Container layout system, which hides section-based templates from the legacy library.
To access section-based templates:
- Go to WordPress Dashboard > Elementor > Editor > Settings > Features.

- Deactivate the Container feature.

- Import the template from the library.
- Reactivate the Container feature.
After reactivating Containers, you can manually convert the imported content into a container structure.
While Containers are deactivated, content built with Containers will be hidden.
Editing or updating pages containing Containers while the feature is disabled may cause container content to be lost.
