Magento Checkout Issues in CSP Restricted Mode: How to Diagnose and Fix Them Safely
Table of Contents Why checkout breaks when restricted mode is enforced The most common symptom...
Introduction
The client was managing two separate eCommerce platforms built independently, which over time led to rising maintenance costs, duplicated features, and limitations on future system development.
The main goal of the project was a full migration to Magento Open Source, along with simplifying the complex two-instance setup by consolidating everything into a single, unified solution and optimizing it into a very fast and efficient Iskra/Sparq platform based on Magento Open Source.
We completed the entire process in about 14 weeks, preserving all key store functionalities and ensuring uninterrupted daily operations throughout the transition.

Accessibility and UX in the Hyvä-Based Store
The shop.tytan.com store was built using our custom solution ISKRA, developed on top of Hyvä (The Sparq for Rapid Hyvä eCommerce). This approach allowed us to create a modern, fast, and user-friendly interface. From the very beginning, our goal was to ensure the platform was not only visually appealing, but above all compliant with accessibility standards (WCAG) and convenient for everyday use, both for customers and for the team managing the store.
We ensured proper contrast and full compliance with WCAG guidelines, making the store accessible to a broad range of users, including those with special needs. The platform is fully responsive, delivering a consistent and comfortable experience across desktop, tablet, and mobile devices.
Performance was another key focus area. The Hyvä-based frontend guarantees fast page loading and smooth operation, directly impacting user satisfaction and sales performance.
From the administrative perspective, the store offers extensive content management capabilities. The client’s team can easily edit content, expand informational sections, or modify page layouts without involving a technical team.
A clear setup of categories, product listings, and filters helps users find what they’re looking for quickly. Navigation is intuitive, making it easy and natural to move through the store.
The result is a modern platform that combines accessibility, high performance, and genuine user convenience.
