Hello, I am now trying JoomSEF and I have problem:

1) when I start use SEF(global SEF URL/enable ) - Links stop working :-/
2) In JoomSEF settings I see that configuration file is write disabled (how can I change it ?)

I don't know if the problem is in some file system rights ? And I don't know name and path of configuration file message that I see in setting...

Can you help ?
