[eluser]Unknown[/eluser]
hi,
happy with codeiginter and it works out of the box on most webhoster.

but lately many webhoster switching to CGI/FastCGI and now its the second time i cant bring
it up.

this is the error log i get from the hoster:

146)Connection refused: FastCGI: "/home/strato/http/fastcgi/rid/53/75/54045375/htdocs/index.php" aborted: read failed (0 bytes) after 2 sec


there is no .htaccess include only the datamapper
