Hi: I am a newbie and looked where I could.
When I did the automatic upgrade to 2.8 it changed my dashboard to just about nothing useful displayed. The closest I could come to correcting on line was to change my Screen Options. I click and it just changes the page info on the top but the screen change options will not show up.
On another account I have I had the screen options open and I changed to one column. Then when I tried to change back to two it only put a blank box on the right and kept the information on one line.
Any ideas? Thanks Larry
