Safari not keeping me logged in

[DuFFy]

So I've noticed in the last two days that I cant keep signed in on my phone while surfing a website. For example, yesterday i was trying to get onto my ebay and signed in. then it would load then reloaded right away as if i never signed in. I thought it was just ebay for some reason. Then just now i was surfing facebook, signed in, my news feed came up, i click to check my notifications and it asked me to sign on again, i did. then i went to click one and it asked me to sign in again. its seems like its something to do with the cookies or something. its set to accept cookie from visited, like its always been. I have a jailbroken 1.1.4 phone, I jailbroke it two weeks ago and its been fine up until the last couple days. Anyone know how i can fix it?
