I have just visited www.libsdl.org and I got this error message:
" Warning: pg_connect() unable to connect to PostgreSQL server: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket “/tmp/.s.PGSQL.5432”? in /home/sdlweb/libsdl.org/web/include/login.inc.php on line 25 "
I think that you already know it but in any case, is just to inform you.
I imagine that there is someone working on it.
