New to TestLink can not edit Requirements

[annoyedintern]

Hey so everytime I go to save my requriements after I edit them I get a Webpage expired notice. This is for both the ones I have imported and the one I have created manually. I don't know what is going on with that. I mean is it something to do with my internet settings or is it something more serious.
Sorry if this seems trivial but I am a first time user, and got this whole thing sort of pushed on me without a clue.

Thanks for any help.
