As mentioned elsewhere (and Dr. Guy said as well) it's probably cookies (although it could be JoeUser being flaky, or your computer rebeling for whatever reason). If it's a new problem ask yourself what's changed on your computer since you were able to log in. But if that was when you last posted an article, well alot could have happened in that time. I would check the browser settings that allow cookies to be saved (which vary by browser). Tools/Internet Options/Privacy for Internet Explorer. Medium security should work, or you could set it to allow all for a test (making sure to set it back after the test). If it still doesn't work with allow all then it's likely a problem elsewhere. Dr. Guy's suggestion about clearing the cookies/cache isn't a bad one, but if you have cookies for other sites (login information for example) you'll lose that. But if you do have other sites that remember your login info then that implies cookies are working properly for you and the problem is related to JoeUser. In any case, hope you get things fixed and feel free to yell at me more if you want me to try and help more.
