Describe here your question/suggestion/issue (expected and actual results):
When I click "delete" to delete a site, it asks me to confirm, and after I click "confirm" it displays "The link you followed has expired. Try again." But then when I return to the list of sites, the site is deleted. So not a show-stopper, but something is wrong.
