XF 1.5 Broken Links on posts

[Ankurmohan]

Dear Team,

In all my posts, somehow the following broken links are generated....The links should just be https://myforum.com/login but the thread url is coming in between.

https://myforum.com/threads/thread_url/login
https://myforum.com/threads/thread_url/lost-password
https://myforum.com/threads/thread_url/register/twitter?reg=1
https://myforum.com/threads/thread_url/search
https://myforum.com/threads/thread_url/find-new/posts?recent=1
https://myforum.com/threads/thread_url/misc/quick-navigation-menu?selected=node-18

Any ideas why this could be happening?

I checked htaccess that seems to be okay.

Many Thanks for any pointers.

Kind regards
Ankur
