Applet viewable when html file downloaded, but not in LMS.

neilhaskins shared this question 2 years ago

When attempting to view an applet, the GeoGebra logo will appear with the little spinner icon below it, but nothing further will happen.

If I check my browser console, I'll see a bunch of errors like:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS header “Access-Control-Allow-Origin” missing).

However, if I download the html file and view the file, then the applet will load properly.

What do I need to change so the applet will work from within my LMS?

Which LMS? Can you provide a link?


The LMS is Moodle. I don't have a public link, but I can attach the file. All we're doing is serving the HTML file to students.


OK I see. You need to update the html to use the supported embedding method - see
