Hi Peter,
Thanks for the quick answer. I think I know the problem already. I think it has to do with TTL. I opened the same webpage locally on the server, in Internet Explorer, and saw the old page. When I clicked on F5, it refreshed to the new one. In Xibo you cannot to a refresh with F5, so that’s why it is still showing the old page.
Now, the webpages are saved .HTML excel sheets with all kinds of production numbers in it, so maybe I can make a change in the XAMPP server (I am using the same webserver for Xibo, as for the 10 webpages).
