Hi, 

I have a folder "websites" with several folders that contain stored websites
with httrack.

When I open the index.html file to browse these, the browser only shows the
header "Index of locally available sites:" and then an empty blue page.

The content is all there, I can go to each individual folder and click on
projects index.html file to open it.

Did somebody experience this? And is there a way to fix it?
