File manager known issue

I am able to log in to 000webhost. When I click on upload files to get to the editor, I am asked for my website name and password. I get a response “Log in details are not correct” Why? Some of my students at school on a different network also get the redundant prompt. Can you explain in simple language what is going on and how to get past this problem? I looked at similar messages and could not understand the proposed fixes.

Thank you.

@mrmark Its a known issue and will be fixed soon
