Can't show two blocks on the same page

Hi, i have a little problem: i just can't show two blocks of ads on the same page. When i put them, one simply desappear. I think that there's sth to do with javascript. Any clue? Thanks a lot.

I notice this issue when working on a local apache webserver, but things work fine once uploaded to a live server. I've not been able to determine the cause of that yet...
