Copy / paste sections between pages

Sometimes, you'll need to combine elements from two or more different imported pages and there's a simple way of doing this using the copy / paste feature:


When this feature stops working, just go to Appearance - Theme Options - Customizations and click on Clear LocalStorage.

If this doesn't solve the problem either, before clicking the paste button, try adding a new empty section and deleting it. Then click on paste and it should work.
