With over a decade of experience in eCommerce and website development, I am confident that I can help you resolve the 500 Server Error issue you've encountered with your updated Prestashop site.

My commitment to customer satisfaction is unparalleled. I will not rest until every problem is fixed and your website is running flawlessly. In addition to my technical skills, I can also support you with any needs in Graphic Designing or Digital Marketing – encompassing Google Ads, Facebook marketing, SEO, and more – as our project progresses.
