I don't know what you mean...
I got this problem when I installed the cms on my server (not local server).
Maybe this code cold help me:
var.usualUrlCharClasses = "[\w\d\%\&\/\\\-\_\+\=\@\.\,\>\<\~]"
server.error-handler-404 = "/sapphire/main.php"
url.rewrite-once = (
"^([^\?\ ]*\.pdf)$" => "$1",
"^([^\?\ ]*\.swf)$" => "$1",
"^([^\?\ ]*\.gif)$" => "$1",
"^([^\?\ ]*\.jpg)$" => "$1",
"^([^\?\ ]*\.jpeg)$" => "$1",
"^([^\?\ ]*\.png)$" => "$1",
"^([^\?\ ]*\.xbm)$" => "$1",
"^([^\?\ ]*\.xpm)$" => "$1",
"^([^\?\ ]*\.css)$" => "$1",
"^([^\?\ ]*\.html)$" => "$1",
"^([^\?\ ]*\.htm)$" => "$1",
"^([^\?\ ]*\.js)$" => "$1",
"^([^\?\ ]*\.text)$" => "$1",
"^([^\?\ ]*\.txt)$" => "$1",
"^([^\?\ ]*\.dtd)$" => "$1",
"^([^\?\ ]*\.xml)$" => "$1",
"^/assets/(.*)$" => "/assets/$1",
"^/("+usualUrlCharClasses+"*)\??(.*)" => "/sapphire/main.php?url=$1&$2",
)
but I don't know in wich file and line I should post it
