I had trouble to upgrade an older installation t the latest version. The fresh 2.4.1. showed a setup screen without the known style sheet and I was not able to access the administration site. The frontend was working. I was then shifting everything to local host and rebuild the site with the new version. There everything worked fine. Shifting it back to the web the same issue. Error 500 and too many redirects. What can I do to solve this problem?
