Thank you for the patch and such, however, I haven't the faintest idea what this patch refers to. It just says index.php. You don't say where this file is, what it is for, what this function does..

You need to actually explain things in a ticket, so that others can understand what you're talking about, exactly. As it is, this says that there's some unused variables somewhere, in an index.php file, on some random site, somewhere in the world. I'm sure that is the case, however, with this little amount of detail, there's not a lot that can done about it.

Here get_location functions which is used for Determine a location for the given parameters.i found this two variable are not use in get_location functions but it is define so this two variable(global $cache_life, $cache_group;) are not use here so we can remove this two global variable for imporvement.
