I'm a new here

Newbie here !!

I have crossed over 50% in this course.

This is very frustrating. Again and again my Bluehost account and my website are after if I make a break for few hours throwing me out forcing me to enter again with my username or my email I registered with and when I fill in these details which are VALID, to the best of my knowledge, I get the message that either my email is "unknown" or my username is "not registered". What Should I do? I cannot progress like this. And the checkbox "Remember me" does not do its job 😒
