Coupon creation redirects to admin home

[froldao]

It never happened before, but now, if I try to create a new coupon code or to edit an existing one, when I click "preview" I get sent to the Admin homepage...

Does the same thing happen on other things in the Admin when you edit?

Did you recently install the Security Patches?

If so, check that you have installed them correctly, in particular the file:
/includes/functions/html_output.php
/admin/includes/functions/html_output.php

yes I have made those updates, and no, I don't notice it happening anywhere else...

Sounds like you've *not* updated the admin version of html_output.php properly.

I guess not :) I did it again and it worked!
