Please consider these issues:
- The FFForums' server database occasionally has problems and sometimes resets. This may be the cause of some of the login issues.
- You will not be able to log in if your browser has been set not to accept cookies.
- You will not be able to be automatically logged in if you have set your browser not to accept permanent cookies.
- You will only be automatically logged in if you check the "Log me on automatically each visit" tick box before you press the Submit button while logging in.
- Although deleting temporary internet files and cookies periodically is good computer maintenance, deleting cookies will of course delete the cookie that logs you in automatically.
- Cookies have a 7-day expiration; you will not be automatically logged in if you have not visited FFForums in seven or more days.
- I am uncertain whether the auto-login keys work for users with dynamic IP addresses.
