Ok...
Most of the time I click I link and get the regular redirect screen (see the first screenshot) but sometimes I get the redirect screen with the encoded URL. (See 2nd screenshot). After it counts down it then refreshes to the same redirector page but now it looks "normal" - i.e. it says being redirected to "http://whatever.com/whatever".
So its like its redirecting the URL to the redirector and then redirecting the person out...
I don't know why it does that... and with this URL:
http://www.insightstraining.com/view...1&categoryID=4
It first redirects with the HEX (2nd pic) and then I get:
"406 Not Acceptable
An appropriate representation of the requested resource /forums/redirector.php could not be found on this server."
99% of URLs work ok.
