I've googled this topic heavily and found a post regarding it on your old forum. I've read trouble shooting chapter, done everything I think of to get my log-in page to work, but still no luck.
I can register without a problem, the activation script works from my e-mail to my site. I've gone so far as to take SHA off my passwords in the database just to make sure it's grabbing the password correctly. But even when I enter the correct user email and password it still says 'Please try again'.
I'd really be great-full for any help I can get on this matter. Here's the link,
