as recommended here I updated to the latest version by installing the German localization instead of the English.
When I just now wanted to add the cookie of a forum to the list of protected cookies CCleaner wasn't showing me that new cookie (than IS on my HD) but instead lots of cookies it already deleted an hour ago!?
I updated to 1.26.218 today and have the opposite problem ... only new cookies are offered in Options > Cookies. The ones that I had before the update don't show.
If I select Cleaner > Windows > Internet Explorer > Cookies, and Analyze, it selects all (both new and old) for deletion.
I cleaned them all out and went back to my Favorites. The new cookies show up in Options > Cookies and can be selected to keep.
