Today I tried to duplicate the look on another server. I exported the style from the above site and then imported it to the new site. No change.
So I imported the ata-round.txt file, clicked "Save changes," deleted the browser cache, and still no change!
juggledad said in another thread:
first off, go up to 3.5.1
next use the delete bfa_ata4 button, then import the ata-round.txt style
Note, you need to haave the ata-round.txt on your local computer
In fact (and this is a bit embarrassing), I mistakenly deleted the bfa_ata4 option in my previous blog and lost the rounded style I had enabled yesterday! And I can't get it back by importing ata-round.txt! Arrrrrgh!
