The URI you submitted has disallowed characters.

This is the most annoying thing. There are no characters in the url that is not allowed. I haven't touched the base files at all, so why is this one so buggy like this? I'm using the latest version of CI and this is the first time I've had this problem... ever!

Can you post an example url that's not working?

[eluser]stuffradio[/eluser]
http://followurl.com/index.php/urls/getpage/testing

That's one of them.

Have a look at the URL which is requested by the frameset:

http://followurl.com/index.php/urls/getpage/<div style=

It contains % and =.

There are error messages in the source code:

<h4>A PHP Error was encountered</h4>
