# cat 
wget -O ntop-$(date +%Y%m%d_%H:%M).php ""

Is this typo ?

!/bin/bash -- Missing #
# 6  
My friends, script isn't working on crontab but it is working manually.

Everythink seems fine but what is the problem!
# 7  
If it isn't the missing # at the start of the shebang line then it could be that wget isn't on crontab's path.
try substituting the full path to the wget binary
