Ok, it looks like MapProxy tries to log something but the logging is not configured. The logging then goes to stdout, but that is not supported by mod_wsgi.


You can look at the log_deploy.ini in the example configuration. You need to load that configuration inside your WSGI application:

  import logging
  logging.config.fileConfig("logging.conf")
