Chuck, I see you are right, but its difficult to know why and how to change this. The pages are exactly the same, with the charset set to Latin1:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
Textpattern is set to UTF.
Err, any idea why with exactly the same files and data, the browser picks up the charset correctly in the old installation, but not the new, except for UTF textpattern?
I realise this now has nothing to do with PhotoPost, but if you or someone else can shed some light I would appreciate it :-)
