My admin bar style disappeared all of a sudden. I see only text ordered up-to-down. There are no problems with the back-end or front-end core of the website. I can see and use the website just fine.
From the front-end, the site looks fine, but there is nothing in the place of the admin bar.
From the back-end, the admin bar is göne, but the links on the admin bar is ordered like a list, and the dashboard page, which normally starts right after the admin bar starts from 20-30 lines below.
As I mentioned, it is only an aesthetics and ergonomy problem. No technical issues. But it is disturbing to scroll down everytime I click on a button on the back-end.
Here is a screenshot. Anybody has an idea?
