I ran into a difficult problem:
carrington seems to ignore a 301 redirection set in the root htaccess file.
I got this:
#RedirectMatch 301 /(.*)\.html$ http://www.site.com/$1/index.htm
(changing url syntax from site.com/title.html to site.com/title/index.htm)
With the old theme this worked without a problem but since I'm using carrington the redirection does not work anymore.
Carrington uses some automatic url suggestion and I could imagine this could cause the problem with the 301 redirection but I haven't found that piece of code.
Thanks for every tip or hint.
