Migration to OpenCart 4
If your online store is still running on OpenCart 1.5, 2.x, or 3.x, you have likely already noticed a decline in efficiency. An outdated software base creates a number of critical issues:
- Low conversion rates: Slow page load times and an outdated checkout process frustrate customers, especially on mobile devices.
- SEO problems: Search engines penalize sites that do not meet modern security and speed standards (Core Web Vitals).
- Management difficulties: The outdated admin panel is inconvenient for managers and does not allow for effective order management from a smartphone.
- Expensive maintenance: Finding a developer to support and fix bugs in outdated code is becoming increasingly expensive and difficult.
Upgrading your online store to OpenCart 4
Speed up your store, boost sales, and gain stability without module conflicts
OpenCart 4 is the new generation of the popular e-commerce platform, created to meet the requirements of modern online business. Migrating to the current version gives store owners a noticeable boost in speed, reliability, and SEO results.
Why store owners choose OpenCart 4
1. Increased speed and performance
- Faster page and catalog loading.
- Improved operation with a large number of products and orders.
- Higher PageSpeed and Core Web Vitals scores.
Result: Growth in conversion and SEO traffic thanks to speed.
2. More stability — no conflicts
- New "Events" architecture for extensions instead of the old OCMOD.
- No need to edit core system files.
- Safe updates and functionality scaling.
Result: Your store remains functional when installing any modules.
3. Enhanced security and data protection
- CSRF tokens, improved authorization, and access rights checks.
- Built-in protection against SQL injections and XSS attacks.
- Absence of vulnerable outdated libraries.
Result: Reduced risk of hacking and fines for data leaks.
4. Modern and user-friendly admin interface
- Faster staff training.
- Easier management of the catalog, orders, and customers from any device.
Result: Administration takes less time — the team works more efficiently.
5. PHP 8 support
- High performance on modern servers.
- Long-term stability and security of the project.
Important: OpenCart 3 on PHP 8 works unstably and requires constant technical fixes, whereas OC 4 is developed specifically for the new standards.
