What version of PHP/CodeIgniter is your application running on?
What's your base_url set to?

P.S.: Hallo von Deutschland nach Deutschland

[eluser]Palroan[/eluser]
my ci version is 1.7.1
and my baseurl is mystite.de/

[eluser]davidbehler[/eluser]
If your URL looks like this: "mysite.de/codeigniter/index.php", then your base_url should be "mysite.de/codeigniter/"

What about your PHP version? There is a known bug with PHP 5.3 and CI 1.7.1 that results in the exact error message you posted: The URI you submitted has disallowed characters.

That issue has been discussed multiple times, e.g. here and [url=http://ellislab.com/forums/viewthread/124643/]here

[eluser]Palroan[/eluser]
yes, i've got php version 5.3
i look into the link and changfe the baseurl.
thanks very much

1.7.1 was released before 5.3, so it's not compatible.

Do you know how to use SVN? On the downloads page there's a link to our svn repository, which has all the required fixes for 5.3.

Welcome to CodeIgniter (ebenfalls aus Deutschland ).

[eluser]Palroan[/eluser]
no, i dont know how to use subversions... on the svn page i dont find the link. whats the name of it?

[eluser]Pascal Kriete[/eluser]
It's linked under "Subversion Server".

The file in question for this particular issue is system/libraries/URI.php.

[eluser]Palroan[/eluser]
and i must save this file in /system/libraries/URI.php?

[eluser]Pascal Kriete[/eluser]
That's correct.

There are a few other things that may throw E_DEPRECATED warnings, but this should get rid of your current problem =) .
