Hi Rui
I don’t think you are quite understanding what the problem is here – let me try again to get my point across.
How I would envisage arrows to work, would be – right facing arrow means go forward, left arrow means go backwards. The Punch theme works in the very same way. The Sazzi portfolio item is the first and the only way to go is forwards using the right arrow.
For some strange reason my clients website has the arrows operating in the opposite way and I need to correct this. My first portfolio item is Mediterranean Inspired and you would expect to press the right arrow to see the next portfolio item, but the website is acting incorrectly and the left facing arrow is the link to see the next portfolio item.
I hope my explanation has helped explain the issue and I look forward to hearing from you.
