[quote author="lifewithryan" date="1201763075"]so do you have a controller called admin.php?[/quote]
no, i think you misunderstood me, 'admin' is my codeigniter folder so my folder hierarchy is like this:

Code:

www.grupofema.com
  -admin
      -.htaccess
      -index.php
      -system
        -application
        -cache
        -codeigniter
        -...

[quote author="lifewithryan" date="1201763075"]is your htaccess file called ".htaccess" (notice the dot)[/quote]
yes, and it is positioned like above.

[quote author="lifewithryan" date="1201763075"]Is your apache configuration setup to allow the use of .htaccess files?[/quote]

yes
