Why is the Page builder add-on deprecated?
The Page Builder Add-On has been deprecated in Debutify Theme 4.0 because of the Shopify Online store 2.0 update.
One of the key features is that you can now add sections to any of the pages of your store, not just the homepage. If you have the Page builder add-on enabled in an earlier version of the Debutify theme, you will get notified that the add-on is deprecated in Debutify 4.0 themes because you no longer need the add-on given the update.
How to Add Debutify 4.0 Theme
Log in to Shopify, click on Apps, and then click on the Debutify app.
Click on Theme Library.
Click Add Debutify 4.0.0
Confirm which settings to copy from the current/older version to Debutity 4.0.0 theme. Click Add to theme library to add the Debutify 4.0.0 Theme.
If the Page builder add-on is enabled in the older version, you will see a notification of its deprecation. Click Add to theme library to add the Debutify 4.0.0 Theme.
