Can't Stay Logged in

Did someone work on mousebits overnight? I know there is alot of remodeling being done to the website.  Last night I had no problem
but today I can't stay logged in.  I even reset my Password. On the Login page, it says:   Note: You need cookies enabled to log in.  How do enable cookies?  I did delete my Temp. Internet  Files last night around 4PM.  I'm sure I was on the site after that and it worked fine untll I got up this morning.  

Cookies by default are enabled, unless maybe you are using an office computer or something.

An upgrade was performed last night at about 6:00 PM MST.  I don't think there is any reason why it should have disrupted your ability to stay logged in.

Is there some sort of pattern how it is logging you out or is it just on occasion every few page browses or something?

BTW, clearing Temporary Internet Files does not usually include cookies.  You generally have to specify that they be removed in a separate action.
