Hi there,
Thanks for reaching out. Please note that we are limited in how much support we can provide for customizations such as this. That being said, I will try to help if I can.
The steps mentioned in that other thread seem pretty straight forward. You say this was working before, but it recently stopped?
Can you share your custom template where you have made this modification? If you can upload it to a sharing service like Dropbox or create a github gist with the code and share the link here, I will take a look at it.
Thanks,
Sky
