Hello, I'd like to offer you my Prestashop skills. I can fix your redirect issue. All I need is access to your hosting administration.
----------------------------
I work daily with Prestashop for over 8 years. I know Prestashop from top to bottom. I am familiar with every aspect of this eshop system. From adding simple features, theme modifications, creating custom Prestashop modules to overriding core files and connecting Prestashop to various APIs.
You can also check my profile on freelancer.com where I have a lot of Prestashop related reviews: https://www.freelancer.com/u/prestashop24.html
Thank you for your time.
Kind Regards,
Jarda Nalezny
