I’m running OpenCart 3.0.4.1 and want to switch over to the “Entry – Advanced OpenCart Multipurpose Responsive Theme.” The store is live, so every existing module, extension, and product/listing record must stay intact; no data loss or conflicts. Once the theme is installed, I’ll hand you a design file that shows how I’d like the new look refined. The focus is layout adjustments on the homepage, product pages, and the checkout flow. Color palette, fonts, and other global styles can stay as the theme ships—just the structure, spacing, and component placement need to follow my design. I expect you to work in a safe way (staging site or full backup first), test across desktop and mobile, and leave all third-party modules fully functional. Familiarity with OpenCart theme hierarchy, Twig, and PHP tweaks is essential. Deliverables • Theme installed and activated with zero data loss • Homepage, product page, and checkout layouts updated to match my design file • Responsive checks and browser tests completed • Clear hand-off notes on any core edits or overrides applied
