most common error is the one with .mcr files, but as you've disabled map-download i can't check
tipp: follow this link to your user-cp and enable "Send me notifications when my world has completed rendering.":

you will get an e-mail notification when your map has finished rendering AND - if there is a rendering-problem, you will receive an error-message which usually helps a lot at finding and solving the problem
