Default URI scheme errors out with: The URI you submitted has disallowed characters.

[GoogleCodeExporter]

Using PHP 5.3.1 and following the install instructions everything works until 
you try and save a snippet for the first time and you get the error: "The URI 
you submitted has disallowed characters."

Following this page solved the problem but it should be addressed in a future 
version of how to get around it.

otherwise, install instructions worked perfectly! :)

I ran into the same issue and I just removed the preg_quote altogether to 
resolve it.  I wonder if an update to CodeIgniter addresses this issue?  Thanks 
for the link, though.

To fix the issue

vim system/config/config.php
in Stikked folder and
comment $config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';
by adding # infront of it as follows.
# $config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

this happens mainly because you have a hyphen in your domain.
commenting and allowing is not ideal, rather making the following changes:

" (assuming codeigniter 1.7.x)

1) in codeigiter system/libraries open URI.php line 189 you’ll find

if ( ! 
preg_match("|^[".preg_quote($this->config->item('permitted_uri_chars'))."]+$|i",
 rawurlencode($str)))

change this code by

if ( ! preg_match("|^[".($this->config->item('permitted_uri_chars'))."]+$|i", 
rawurlencode($str)))

2. Now another changes in your system/application/config/config.php file. Go to 
the line 126

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-';

change this code by

$config['permitted_uri_chars'] = 'a-z 0-9~%\.\:_\-';

After changes the code, save the file and refresh your browser."
