This used to work very well, I found it really handy, thank you. But recently it stopped working altogether
When you enter the code it just does nothing, as if you'd entered a bad/non-existent code
I use a few other scripts on SG (plus ESGST installed as an extension) so it's possible there's a conflict, if not I guess maybe some part of the website may have changed?
I uninstalled it a few days ago, then installed it again today just to see if it magically worked again.
And it did, but only once. Now it's gone back to being non-functional again...
