Small problem when updating admin section

[Guest facethefuture]

Hey all

When ever I edit my admin section, e.g. add a new product, when I got back to my shop and click on any link, it just takes me back to the home page.

Now, my shop still works, however, today I have been adding loads of new products so this has been causing a problem for people using the shop.

Does anyone know what's causing this, and how do I fix this?

I would really appreciate if anyone has a solution to this.

Thanks

Mark
