forum not recognizing history??

For the last 3 days now, every time I bring up this site, I have to relog on. Even if I check the remember me box if I close out the site and reopen it, I have to log on again.
It accepts my logon every time, and in the past it always brought me up every time I opened the site, but for whatever reason now it won't. Same computer and same logon info???

Anybody else experiencing this or have any idea why?
