Have you confirmed that this is a theme issue by switching to Twenty eleven and then trying to login with Chrome & Firefox? Frankly, it sounds more like a local browser issue to me.
Hey esmi, thanks for the quick reply. I am not 100% sure. I have tried several others and they work more, but not completely. With your theme, I simply cannot log in with chrome or firefox (I click login and it does nothing). With the others (including 2011), I can log in to dashboard, but when I go back to website, it is no longer logged in. I will seek help through wordpress forums first I guess. Sorry for the mis-post.
It’s not my theme. I just happened to be passing and know something about the way in which themes work. And this didn’t sound like a theme issue to me – especially as it is browser specific and will have been extensively tested (by users) in Firefox & Chrome.

Then this pretty much confirms that this is not a theme issue.
