Whenever you upgrade your theme, there might be some changes in the database after the update or perhaps your Advanced Color scheme or Basic Color scheme might not apply due to changes in the structure.
In that case, go to the Theme Settings > Data Upgrades tab and click on Data Upgrade to make your website compatible with the latest theme upgrade.
If your color scheme still appears to be broken by the update, try Going to the Theme Settings > Appearance Settings and click “Save Changes” manually.
