Hai folks,
i intalled joomla and every thing going fine.
but when i turn off the author name, time and date etc for the articles through article manager > parameters, it don’t apply the changes even when i saved 
please help!
ok folks, i made a mistake, i did not select any article and made the changes, what i did was just went there and clicked parameters and made changes. so not applied to any. now problem ok !
