It is more of a login issue with your cookies.

Under the "MY HOME" tab is a "Main Configuration" panel. The bottom line is titled: Maintenance and has a selection "My Cookies"

Select that and then select the option to "expire cookies". You will be logged out and it should clear all of the session cookies.

It is the session cookies that can become corrupt and cause weird problems with login and display.

I have had a periodic problem with my Droid phone but no problems with my iPad.

Any problems, drop me an email as I periodically have to expire cookies for someone's login.
