XF 2.2 Forum Board link from admin issue

For some strange reason when I'm in the admin panel and click on my sites link to go back to the forum it takes me to forum/index.php but I want to make it point back to my forum. Where can I edit that link so I can put the correct path to the forum? I click inspect and it states header buttons p button. I can find that anywhere. I type it in search but nowhere . Thanks
