I uploaded a site I made (you can see it at www.qbsoft.ca) and it worked elsewhere.
I have several small links at the very bottom of the pages that each include standard Href tags that will not link? Any idea why? It worked fine when I was hosted elsewhere.
Can you post your sourcecode?
Try disabling the 000webhost banner via general settings on 000webhost.com
The webhost bnner apparently blocks the entire bottom row from being clickable I discovered.
It cannot be removed since it is added by the host.
