I can't log into any of my accounts.

When I type in my username and password to any of my accounts it says "Login Failed"  Please help, and I don't understand the html language that I see many speaking here lol.  Please help me in layman terms.

Do you run your own Roundcube install or are you and end user?

If you run your own install then check the Roundcube error logs (typically in [rc root]/logs/errors) and check your IMAP server logs.

If you are an end user then you need to contact the people who run your email. Roundcube is the name of the webmail software they are using, it is not an email service.
