Login button redirect to site login not WPlogin

Is there a way to map the LOGIN button on the bottom of answers to redirect to my site’s login? Right now, it brings up the WordPress login – how can I solve this? I have BuddyPress and MyListing associated with AnsPress, is there CSS I need to put somewhere (coding is not my area of expertise, a simplified solution or detailed explanation of how I am to modify the code to achieve this result would be most preferred).
