Well a little progress to report.
I did go in through Cookies and list the the base URL of
as an allowed cookie. This had the effect of each time I go on the forum the log in information will be set and I can log in.
Now each time I change pages that screen will appear again with my information and I have to log in again.
What has changed is the fact that the log in information has been retained but I still have to log in at each page.
As for removing old Cookies, that is waht started this problem.
We are getting closer though. It clearly has to do with Cookies but witch one is needed tobe allowed has not yet been defined.
