Page After Logging In

For some reason, when a member logs in to the member login page, it goes to a white page with a box at the top that says “You must check that box to say you’re not a bot.” but there is NO box there nor did I intend there to be. I refresh the page and it goes to the member profile page instead of the page I wanted it to redirect to. I’ve already downloaded the add on for the login redirection. I just don’t know why it goes to a page with that message when there is no box there to begin with. Please help!
