My suitecrm page keeps opens the mobile version on the login page

When i try to log in my suitecrm page on my desktop, i keep getting the mobile version. When i log in, it opens a broken page.
The page works fine a couple days ago on my desktop. All of a sudden i get this problem.
I tried it on other desktops and other browsers and other layouts, but keep getting the same results.

Can anyone help me fix this?
