For me, the CSS of the page has been hacked for weeks. Only the start and login pages have the correct design. All forums, threads, the profile etc. consist only of white background with blue links and rudimentary elements. It is completely irrelevant which browser (Safari, Edge) and which device (PC, Mac, iPhone, iPad) are used. At the beginning the page looked still correct in the mobile view, but that is now also over. A logout and deletion of the cache brings the page a Don’t look back in full beauty.
