Private_Message link broken

Hi Folks, It seems like on opigno 2.4 the private message create button redirects to a url which is incorrect. for instance if the site is hosted like so : http://localhost/op and when we navigate to http://localhost:8089/op/private_messages and click on new Message the URL redirects to http://localhost:8089/private_message/create which is incorrect. the correct URL is http://localhost:8089/op/private_message/create How do i fix this? Thanks
