I created a personal webpage on notepad++ and created links to 5 different leaflet maps on it. it works fine when you run it from notepad++. The problem is when I used FileZilla to put my files onto the school server, the leaflet map links on my webpage do not work. If I click on the link it just shows the map title not the actual map. I get errors sayin... Mixed Content: The page at 'https://tigerweb.towson.edu/sphill16/map1.htm' was loaded over HTTPS, but requested an insecure stylesheet 'http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css'. This request has been blocked; the content must be served over HTTPS.
You're not the first person to encounter this issue, but there is an easy fix. The cdnjs service hosts copies of all versions of Leaflet and serves them over https:
So just replace your links with the cdnjs versions, and you should be fine.
Another way would be to download the Leaflet library files and place them in the same directory tree as your local web page, perhaps in a subdirectory called
leaflet (or whatever you like, really). Then you can change the references in your HTML to point to those:
<link rel="stylesheet" href="leaflet/leaflet.css" /> <script src="leaflet/leaflet.js"></script>
and upload the whole project including the directory with the leaflet library files. Either way will work.
