I decided to switch to www.chihuahua-puzzle.com
after reading the discussions about security. My profile was still automatically logged in at the alternative site, but for some reason 'List by plays' was not operating. I clicked the red 'List by plays' option, and the box containing the word list popped up as normal. However, when I clicked the 'x' in the top right corner to close the box, the site switched back to "Not secure chi.lexigame.com". I tried this several times with exactly the same result.
Do I need to clear cookies, or is it something else?
