How To Restore Design Changes
Changing the theme will override all your custom pages in Customize area for all languages. So, if you have a customized code, all changes will be undone.
If you've switched themes and need to undo the changes, simply go to the Revisions section and restore the changes for each document.
If you are not sure how to restore the changes, don't worry! Simply send us a customization request and our team will take care of everything.
