Ok try this,
you have to exit enhanced mobile view and enter the desktop version, then go to settings in upper right hand corner, click on it, then when the new page loads, go to general settings about 1/2 way down on the left hand side of the page, click general settings and then scroll all the way to the bottom of the page, look for IP authentication and make sure little box next to it is not checked, if it's checked, uncheck it and then click save changes at the bottom
of the page.
if the box next to it isn't checked, try checking and then unchecking the box and then hit save changes.
hope it helps
