I've actually fixed it myself, I decided to get drunk yesterday (literally) which made me go on a google spree to find the issue.
All I did was go into the navigation tab in admincp and set the forum as default.
Which now it works, thank you for making an awesome plugin :)
When I installed the SEO i noticed that my forums are no longer accessible by just clicking the forum link on the nav bar, i do not know how to fix this. When i removed the seo it started to work again after i rebuilt the forums and thread links. Is there anyway to fix this with seo installed...
