Hello Mohit

Thank you for this. Will it go to functions.php?

@thehoundproject Yes you have to put his code into the functions.php of the current activated theme.

Hi there!

We haven’t heard back from you in a while, so I’m going to go ahead and mark this thread resolved. If you have any other questions, please feel free to start a new thread!

Hey guys,

I tried to add the above code to my functions.php and the system said it was rolled back, as in couldn’t save changes as there was a mistake in the code.

Could you help out?
Many thanks.
