Hi folks,

I have been trying since last night to get this working, by changing browsers and computers.

I wish to update a signup for a mailing list.  I click Contacts -> Manage Lists and then select the list in quest High-Space (325).  The page that loads is empty of all details - I just get the stardard campaign menus, but nothing inside the page.

This happens in Chrome, Firefox and Edge. 

Please assist.
