Hello,
For chunk loading: open your world folder from the control panel. Inside, you’ll see several folders, look for one called serverconfig.
In that folder, find the config file named ftbchunks. Open it, and you’ll be able to enable chunk loading by setting force_load_mode to "always", you may need to search for force_load_mode whilst inside of the config.
For the map: if you press M, does the map show up on the screen?
