You don't need all these things to be written in conf file just use following
server=1
daemon=1
rpcuser=<user_namer>
rpcpassword=<password>
rpctimeout=30
if connecting from remote host do add following line
rpcallowip=<remote_ip_address>
save and exit from conf file and restart daemon by first stopping it catecoind stop and then catcoind start
