How to logout? after protecting the page I put my info for testing

Hi

After protecting the page, tried to access the page, it showed up a form, I just filled up the form, and hit submit. This is not letting me go further, getting the message "you are already login"

Not able to go further.

Can you share my desktop and see the issue?
------------------------------------------------------

My scenario is like this

I have a page which has to be protected with the visitors. This have a video and other stuff which will be regularly updated.

We have three types of subscribers
1. first time visitors (trail subscriber) want to give 15 days trial subscritption.
2. We have list of broker who are associated with us(have account with us)
3. people dont have account with us just want to be a subscriber

both 2 and 3 have 30 days subscription

thanks
