Hi there,
Do you have the “WPSP Open Wrapper” and “WPSP Closing Wrapper” Elements in “Appearance > Elements”?
If not, you need to create them:
1. Add a new Hook: https://docs.generatepress.com/article/hooks-element-overview/
2. Add the content:
<div class="wpsp-content-wrap">
<!-- Openeing wrapper -->
3. Set the hook to “Custom Hook” and use this hook: wpsp_before_header
4. Set priority to 15
5. Set Display Rules to Entire Site.
Then, add another hook:
1. This content:
<!-- Close WPSP Wrapper -->
</div>
2. Custom Hook: wpsp_after_content
3. Priority: 15
4. Entire Site
