Hi all,
a user has problems with logging.
The registration did not cause any problems,
With IE8 he can log in, but shortly after flying out again.
Firefox goes with anything.
Can it be that he has carried out registration "online" on AOL? And therefore another Log is suppressed?
I suspect that the "online" registration, a cookie is written, the changes caused by the permanent IP these problems.

In the log files is to see that the IP seems to change constantly.

there is an option you may have set that ties cookies to ip addresses. if that option is set the ip address must be consistent for the duration of the user session.

thanks for the quick help.
I found the option and disabled
if it worked, I'll report here even when the user is back on.
