when going from local to distant, get 404

[bagou01]

Hi
i developped a site using categories and sub-categories in VM, and it all worked out on local.
so i jump the bridge, install akeeba, create my archive, upload it, install it on my server (ovh), test it:   the site works, but then, when i try to click on a VM category, i get 404 errors...
the only difference i guess is between PHP (5.3 on local and it works, 5.2 at OVH and won't work)

i also tried manually without akeeba, but same issue.
does anyone know where this could come from ?
thanks a lot in advance because i'm kind of stuck here...

i found the solution,
i had to remove the index.php from the URL using .htaccess   and it works now...
i don't know why, but it didn't work without   on the fly   write of the urls...

weird
