when login using an admin userid, get taken to 
https://purplechips.com/login/?testcookie=1&redirect_to=https://purplechips.com/wp-admin/

a page with nothing on it. To get around this, have to go again purplechips.com which now takes you to the landing page.

This is a new behaviour ssen in the last few weeks.

Also a question from John - when are users (incl admin) auto logged out? Seems to happen randomly.
