Can't get logged in??

As I can understand your issue, you are being logged out constantly from your account.

Does this happen when you perform any action or while trying to do something on your account? 

May you please try using incognito mode and see if this is a cache issue? 

Using incognito will help yo load a fresh copy of the site and you should not experience the issue.
