404 is given when trying to access existing controller in CodeIgniter

I am working on a fairly new install of CodeIgniter 2.0.

I have a htaccess-file containg this code

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

Going to the URL http://www.estiem.no/ESTIEM/CI/ works, but http://www.estiem.no/ESTIEM/CI开发者_C百科/site/index does not. It gives a 404. The controller Site exists, and contains the method 'index'

Any ideas what might be wrong?

You need to remove / from index.php

RewriteRule ^(.*)$ index.php/$1 [L]

It is a htaccess problem, back when everyone passed that code around we found that a lot of hosts didn't like it and you could hack it with a ? or this or that until it ended up looking like a jigsaw puzzle (the condition that is) but using a brilliant htaccess (not sure who the first was but like 500 have taken credit) you will never have to change it again (well not never but it will work 99% of the time un edited):

# Customized error messages.
ErrorDocument 404 /index.php

# Set the default handler.
DirectoryIndex index.php

# Various rewrite rules.
<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>  

Trust me I have had the same issues and spend hours on google when i should have come here or even the CI wiki (since that is the first place I seen it), you would not believe how many issues are solved in CI with just that bit of htaccess. they really should add it to the repo.

I just noticed that since you have your CI install in a subfolder, you need to account for that in the .htaccess rewrite:

/ESTIEM/CI/

So your .htaccess will look like:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /ESTIEM/CI/index.php/$1 [L]

That should fix it (sorry late edit, due to @BrianOrtiz 's comment)

Try to access the controller with: localhost/site/index.php/controller

If that does not work maybe because the CI is case sensitive

• localhost/site/controller == c:...\site\controller.php
• localhost/SITE/controller == c:...\SITE\controller.php

else

<?php

controller Mycontroller extends Controller {

}

?>

will be named mycontroller.php in the controllers folder

If all else fails replace your htaccess by this:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
