Some Zip Shp files not loading

[8dgeSolution]

Hi Calvin,
I have some shape files which load on your website but not on my leaflet app.
http://leaflet.calvinmetcalf.com/
I am using the leaflet.shapefile plugin and shp.js .
I saw that your website only utilise the shp.js file... is that a better option ?

var emRegions = new L.Shapefile('/geoJSON/EM_REGIONS.zip', {
			onEachFeature: function(feature, layer) {
				console.log(layer);
			}
		}).addTo(map);

are you getting an error in the console or the network requests?

Same here! Working on your website but not with your github release (tried to overwrite congress.zip file).
I tried to use a shapefile from the following page: https://www.suche-postleitzahl.org/plz-karte-erstellen

Used shapefile params on the website: Gebiet: 5-stellig, Format: Shapefile, Genauigkeit: sehr gering, Projektion: EPSG:4326 - wgs8. Than click on "Karte erstellen" and download the shapefile on the right side.

No error in the development console.
