Huge map not rendering Archived · read-only

My map hasn't rendered yet. It says "Processing : rendering maps for:". I have waited for an hour now, without any progress.

Are you closing the tab before the map is successfully uploaded to our website? You must keep it open until it is fully complete, since your map is 1.3GB in size it may take a while.

Yes i did, i reuploaded it a few times, because when the rendering is "done", it shows a white screen instead of the map viewer. The latest version i uploaded is still rendering, i uploaded it about 16 hours ago...
