I do not claim to know how rememeberme is implemented, I wish someone will explaine it to me. The wiki page is not help, other than tell you to check on or off the option. So much so, I sent you a paragraph that later on you deleted because you did not understand what it meant.
One thing is for sure, I don't have a cookie for my site. I have a cookie for the forum, one for DOKUWIKI, and one for my server provider.
After I added manually the cookie for my site, it worked. It is clear that DOKUWIKI was looking for a cookie that did not exist.
Furthermore, there is glitch in DOKUWIKI somewhere because I kept using the remember me box at login time, and obviously, did not creeate the cookie.
Meanwhile, my solution works, and it has a plausible technical explanation.
