Turned out I had added some custom css that made «search» remain expanded. Everything is back to default after removing the code.

BTW, if anyone visiting here should want to keep the «search» in expanded mode, here’s the code to add in:
– Appearance > Theme options > custom CSS,

input.s {
 text-indent: 0;
 width: 100px;
 border-color: #eaeaea;
 padding-left: 10px;
}
