I was in the dashboard and went to Screen Options and tried each of the 4 column number choices. I set it to single column, but when I set it back to 2 columns, all the columns stayed in single column format. I moved them from the bottom of the first column to the top of the second column manually, but when I went to another page and came back, it was back in single column mode again, and the setting was still set at 2 columns. There is no “save” button that I can see.
Any idea why this is, and how to correct it?
