How do I reset my development pages in Customer Portal to what I currently have in production?
Customer Portal, End User Pages
To reset the development pages to the current production pages simply copy over the files and folders (pages and widgets!) in the production folder back to the development folder.
We recommend that you make a back up of the current development folder in case you need to restore or retrieve something after the overwrite is completed.
