Can not simplify admincp url path
 

I have a issue with the admincp only loading if i use this path /core/admincp it will not load if use the site url .com/admincp and If I make a change in the admin panel I get a page can not be found error I have checked my config file and the path in it is set to site url.com no trailng slash or anything else added to it..
the url for the site is set to the site url.com and the site url.com/server.php path is /home/whiskey/public_html
what am I missing ?
