External Links work in Preview, but not once Published

Hi guys,

we were about to upload our elearning modules to our website, no LMS.

I have a couple of external links which work just nicely when I preview the file, but once I publish it, none of the external links work anymore.

Now, I am just testing it from my computer once published using the story.html file and it is not hosted on our website yet. Could that be the reason that the links are not working or do I have to change something somewhere in the background?

Thanks so much for your help,

Bianca
