In the creation of a custom portfolio (i.e. without templates), a user is unable to go back to the intro/information page when in 'Step 2 of 3: Design'. Clicking the 'Back' button, gives an error: 'At least one page is required'. The user needs to create the page before being able to go back to the intro page. Screenshot attached.
Steps to reproduce:
1. Login as CIG Participant in Portfolio site
2. Click 'Portfolios' from the 'Design & Publish' area.
3. Click 'Add'
4. Select 'Design your own portfolio'
5. Click 'Continue'
6. Provide a title
7. Click 'Continue'
8. Click 'Back' to go back to the first page where the title/description/comments are set up. The warning message appears that 'At least one page is required'.
