Buddypress won't recognize login.

Hello,

I just installed Buddypress after a long time of not using it. I was pleasantly surprised with how smooth the installation was. Everything was working fine, until I tried posting a test reply to one of my test posts. After logging in, I navigated to the post and clicked on the reply area to start typing, but as soon as I did, I was asked to fill out my login info or log in using a social network.

Any ideas on how to fix this?

Thanks in advance.
