Description of problem: In Site Redirects and Export/Import portlet, the close button in the corner of the Import Site dialog does not do anything. Steps to Reproduce: 1. Start the portal, sign in as root. 2. Go to Group > Administration > Site Redirects and Export/Import. 3. Click on Import Site/Space. 4. Try to close the dialog with the "X" button. Actual results: The dialog remains open. Expected results: The dialog is closed.
Removed "X" button from modals, as there are "Cancel" buttons available. Also clicking on the background won't close the modal anymore, to make the user perform a choice on the "Cancel" vs "Save/Select/Delete/Import" buttons rather than the ambiguous simple modal close.
