Error 404 Page Not Found --> js

[eluser]skunkio[/eluser]
Hi all,
I have configured today MAMP on my laptop in order to have my site accesible even locally. I have modified my .htacces file, created my db unders MAMP and everything seems to work properly except for some js files.
Checking my site I have tried to login (login calls a js) and it's not working. Having a look into my log file I noticed the row below

Code:

404 Page Not Found --> js

Seems like that my js file is not called or the link is not recognized.
Checking on internet I have found another post with the same same so I have checked my base_url() that seems to be ok. Moreover, if I recall my js file with the same link is inside the page that calls the same js, I'm able to access on it and see its contents. I guess there are no issues with the link.
Is there something more that I can check?

Thanks in advance
