Captiva uses Advanced Custom Fields to manage Page Settings. If you import the demo data for the theme you will obtain these fields automatically.

If you choose to setup Adrenalin without the demo data you can import the Page Settings fields by importing the Page Settings XML.

To import this file, go to

Tools -> Import -> WordPress. (Install the Importer plugin if prompted)

Select captiva_pagesettings.xml (attached)

You should then see page settings as follows

If this does not work:

1) Go to 'Custom Fields'
2) Delete any fields that are there
3) Also remove them from the trash/bin - this is important
4) Try the import again
