Permission denied error on reloading the Parent page from child page

Hi All,

I am trying to reload the Parent page from child page on save.  I am using the below code to refresh it.

window.parent.opener.location.reload(true);

This code is working fine for the first time I save the child record. But if i am staying on the same child page and modified something on the page then saving the record. now i am getting the error as Permission denied.

This error is coming because, in the code "window.parent.opener.location.reload(true)" is not able to find location value.

the location value is coming as {...}

Any help is appreciable.
