Pages not updating on other computers or in incognito mode.

I have reacently run into a problem with my new site https://www.ensemblerex.no/.
The last few changes I have made does not show when i try to open the page on any other device. Changes only show on the computer i used to make the site. When I open the site in incognito mode it does not show the changes.

Example is the footer text. On other computers it shows the footer text to be:
Copyright © 2020 St. Hallvard-guttene. Alle rettigheter forbeholdes.
Utviklet av Bernd Klare

The footer text should be:
Copyright © 2020 Ensemble Rex. Alle rettigheter forbeholdes.
Utviklet av Bernd Klare

Any help to figure out what I have done wrong is much appreciated.
