In some instances, a new member here may have registered properly, but finds that after they log in, whenever they change a page, they get presented with another prompt to login again.

In cases of this nature, the most common problem is that the security settings in the browser are set too strictly. Cookies are being blocked between pages, so as soon as you change a page, the system believes you are no longer logged in. Simply reduce the security setting in your browser and it should straighten right up for you.
