Script not found or unable to stat, one page and not others, same permissions

On a new installation of Ubuntu 14.04, I copied several php files, they worked fine in another computer.

The strange thing is almost all pages are showing right but with some of them I get 404 Not Found.

Error:

[Mon Aug 11 14:46:58.581444 2014] [:error] [pid 12123] [client 172.18.0.36:55110] script '/var/www/garantias/imprimir_solicitud.php' not found or unable to stat

From apache2.conf:

<Directory /> Options FollowSymLinks AllowOverride None Require all denied
</Directory>
<Directory /usr/share> AllowOverride None Require all granted
</Directory>
<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted
</Directory>

I found my mistake, Now I have to use in the address the name of the file exactly as it is. Before I could use

sistemas/garantias/imprimir_solicitud.php

and it would show me the page, now I must use the name as it is:

Notice the capital I in word "Imprimir"... that was the problem.
