My Prestashop store needs an urgent cleanup. Right now the product pages show layout glitches, the checkout occasionally fails, and overall loading times feel sluggish. I want every major touch-point—the homepage, individual product pages, the full checkout flow, and any templates they rely on—reviewed and fixed so the site looks sharp and works flawlessly on both desktop and mobile. Here’s what I expect to receive: • Visually corrected product pages (images, variants, tabs, prices and any custom modules displaying as intended). • A checkout process that completes without errors, including payment, shipping and confirmation emails. • An optimised homepage and global layout free of broken elements or misaligned CSS. • Speed improvements measured after your work (server-side caching, database clean-up, code and asset minification, CDN or other techniques you find appropriate for Prestashop). • A quick final sweep of the rest of the catalogue and CMS pages to be sure no hidden issues remain. Access to the back office, FTP and database will be provided immediately; please be comfortable working with Prestashop’s theme system, PHP, Smarty, MySQL and front-end tweaks (HTML, CSS, JavaScript). Share a brief outline of how soon you can start and the steps you’ll take so I know we’re on the same page. Unfortunately, I had entrusted the project to an Indian company, Pear Organization, months ago. Not only did these individuals fail to complete the PrestaShop update to a more up-to-date version, which has been dragging on for over four months, but they also managed to ruin the store's visual appearance and functionality. I'm leaving the website address www.bbdesign.store so that anyone interested in the project can check the situation and give me an estimate of the time and cost.
