I am looking for the file where I can edit the Coupon Code text.
What I want to do is remove the 'Apply Coupon' text & replace it with 'Apply Members Discount'
The 3 instances of text I want to edit are:

Apply Coupon Code
Apply Coupon
Apply Coupon

The last Apply Coupon text is in the button.

Where is the file I need to open to edit the above lines of text?
Or
In the case of the button;
Where is the image for the Apply Coupon button?

Image capture below....i want the green bar at the top to be full width.....but still place logo in same place as the template design

Using HTML5 theme I have already changed the background colour of the header to match the background colour of my logo.

Currently there is a gap of white space left to place a logo in.

I still want to place my logo here but, I do not want the white space in the background.

Is it possible to extend the coloured header background to full width?

Is this Indonesian language folder available?
I would like a copy of this if possible
