Recent changes (https://phabricator.miraheze.org/T10430) are working.

There was an error displaying maps on the phone. The maps are not displayed because the map tiles have the address: https://tile.openstreetmap.org/./14/9000/5218@3x.png?lang=pl

@3x is redundant here because it causes an error.

To disable this, please add the following entry to my wiki lebork.miraheze.org in the LC.php file:
$wgKartographerSrcsetScale = 1;

This will display the maps correctly.
