Is there a reason, perhaps related to the Opera browser, which keeps me logged in even after I perform the Log Out/All cookies cleared routine?

Following and , here are concise, practical checks and explanations for why a browser can still show you as "logged in" after using the site logout or running a cleaner.

Try these diagnostics first:

  • Reproduce the problem in a private/incognito window. If the private window behaves correctly, the issue is persistent site data in the normal profile.
  • Open DevTools and inspect the site’s stored data (cookies, localStorage, sessionStorage, IndexedDB, Cache Storage and any service workers). Clear only that site’s data, then restart the browser. See the DevTools storage guide: .
  • Disable or pause any system cleaners (e.g., CCleaner) and re-run the site logout/clear to see if the cleaner’s settings are interfering or excluding items.
  • Test with a fresh browser profile or a different user account to rule out a corrupted profile. Back up bookmarks/extensions before removing profiles.

Why this happens (short, factual summary):

  • HTTP cookies can be persistent (expiry dates) or session-only; clearing cookies removes those, but other storage types remain. See HTTP cookies.
  • localStorage/IndexedDB are independent of cookies and persist until explicitly cleared, so a site can re-establish a session from those stores. See Window.localStorage.
  • Service workers and the Cache API can supply cached content or state even after cookie removal; unregistering service workers and clearing cache can be necessary. See Using service workers.

Cautions and next steps: check cleaner settings for any “keep” lists, back up your profile before deleting files, and if the behavior cannot be reproduced in a fresh profile, prefer creating a new profile rather than surgically deleting files. If a reproducible bug remains, gather exact steps and browser version and report it to the browser vendor.

Hmmm...you've pointed me in the right direction, perhaps, caper. FF and IE don't see me as logged in, but Opera does [still...]. So it could be a cookie failure in Opera.
... and so it was. One was stuck, retaining the login after I "logged out"; CCleaner wasn't removing it, either... I don't know why not. But a more direct approach worked.

ccleaner as now when you install it about keeping good cookies when a scan is done may have something to do with that ,

What's happening is that the Opera cookie file was poppping in two places [the default folder and its parent folder], both files a bit different in content. I deleted both files, problem solved.
At the moment it is not using the default location, only its parent folder.. I guess that's why CCleaner was missing one file before. But why Opera was writing to the "extra" file and then not letting an instruction from Daniweb remove an entry I don't know.
I deleted the cookie file again, and upon opening Opera it again builds only in the parent location; CCleaner deals with it correctly now, also??!! .
I'll drop them a word at Opera... they're hot on stuff like that.
