In /system/application/config.php, I tried this

Code:

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

and this

Code:

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

For both, I get this error:

Code:

A PHP Error was encountered

Severity: Warning

Message: preg_match() [function.preg-match]: Compilation failed: range out of order in character class at offset 18
