Pages not working

Hi, i have a problem recently, my pages are not working anymore. I found out about this when i created a page called Shop, and i clicked to see it and it brought me back to the main page, then i tested it out on all my pages and the same thing happens it always brings me back to the main page. Same thing with the comments i click them and they just refresh the page. I am using wordpress 2.7 and my site is https://www.soccer-central.tk

any help please?
