Disallowed Key Characters that don't seem to be able to fix in config

Hi shwonkbc and welcome to the CI forums.

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-=,'; (added a comma).

CI is still giving me the Disallowed Key Characters message. What can I do to fix this?

What happens if you add the question mark? Normally we don't like question marks, in CI-land .. not sure if that's what's giving you grief (should be allowed straight through). Just absent an error that says explicitly 'I don't like that , that's there' it'd be nice to rule it out.

I've had weirdness with trying to get the permitted_uri_chars to allow ( and ) characters .. but haven't investigated it properly yet. I suspect it's not an oft' used feature.
