Have you made changes to your Catalog or created a new one but cannot save the changes? Do not be scared. There are some steps you must follow to save your Catalog without any problem:
-Make sure your Catalog does not have white pages. If you have deleted products or images and left white pages, you must make sure to delete those pages.
-If you create new layouts and use them on some pages, do not delete the original or delete cells from the original, as this will cause the app to identify the page as blank, and you will not be able to save your changes.
If you still cannot save your changes after doing all this, do not hesitate to contact us, and we will help you.
