Homepage: navigation on the bottm doesn't work

Hello,

I have a problem on the bottom of my homepage: http://www.differ-allemand.com:
When I click to the numbers of the pages, a new page is shown up, indicating a new page number – but the same(!) articles as on the homepage.
Could anyone help me
– either to resolve this problem completely (= best solution)
– or to delete the function that shows up the numbers on the bottom (= OK, because I have enough links otherwise on my blog)
Thank you in advance for your help.
