wiki log in: "Resource available only to logged in users"

Based on visiting https://www.postgresql.org/account/profile/, this Chrome
profile is logged into my community account.  However, if I visit
https://wiki.postgresql.org/wiki/PostgreSQL_18_Open_Items and click "log in"
or "view source" I get:

  Error 403 Resource available only to logged in users
  Resource available only to logged in users
  Guru Meditation:
  XID: 391363

I get the same in a Chrome incognito window.  I've not seen this error before
today, though I've likely not logged into the wiki since before the PostgreSQL
18.0 release.
