Account link wrong

Dear

When I am on my homepage, and I go over the menu of “My Account” and I select a sub menu like “Downloads” I got redirected to a blank page.

But whilst I am on the “My account” page and I choose the “Downoads” section on the left sidebar it seems to work.

Anyone knows how I can edit the url links of the menu of “my account”?

Sebas
