STEPS TO REPRODUCE

1. Login with Admin
2. Go to a page (non terminal)
3. Click 'More actions > Export'
4. Click on 'Other Formats'
5. From 'Select the pages to export:' drop-down select 'Created pages' or 'Created and modified pages'
6. Select back 'All pages' from the drop-down
7. Click 'Export as XAR' or 'Export as HTML'

EXPECTED RESULTS

The page is exported as XAR/ HTML (or the 'Save As' download box is displayed, depending on browser's settings).
