“Wide” layout not working

Hi, “wide” layout is not properly working and I believe it happened after one of the last updates. Before it was showing it perfectly, now it seems similar to 1440 boxes  even with some space on both left and right borders. If you look at the attachment, for example the logo should be near the left border of the screen, but unfortunately now it is more closer to the center. I would highly appreciate your advice. Thanks in advance and best regards
