Issues with Biology thread

[Kyleg]

I'm currently attempting to make a post in the biology section but an unable for some random reason! everytime i click on the link, when it directs me to the biology section in the top right corner it no longer shows me logged into my account, i then try and make a thread so it asks me to log in. I enter my details it redirects me back to the biology page and voila i'm still not logged in BUT i then click onto the homepage and it says i am logged in. only the biology section doesnt recognise me as logged in.

Anyone else had this issue?
