Abdulgani Tumbi is a Joomla expert with over 12 years of experience in website development, upgrades, and custom solutions.
Whether you are planning a new website, upgrading your current setup, or handling ongoing maintenance, the right expertise plays a critical role. Without it, even small mistakes can lead to broken features, failed updates, or complete site downtime. As a result, making the wrong hiring decision often becomes costly. This guide, therefore, helps you avoid those risks and choose the right professional.
The Risk: Not Every Developer is a Joomla Programmer
One of the most common mistakes is hiring a general PHP developer who claims to handle Joomla projects. While such developers may be comfortable writing code, they often lack platform-specific knowledge. Consequently, this gap leads to serious issues over time.
For example, here is what can go wrong when a site is not handled by an experienced Joomla programmer:
- Updates may break the site due to unsafe overrides or outdated extensions
- In some cases, permissions, menus, or SEF URLs stop working correctly
- Additionally, extension conflicts can introduce hidden bugs
- More importantly, security vulnerabilities may remain unnoticed
- As a result, SEO and performance issues start affecting visibility
When these problems arise, businesses are forced to search for a real Joomla expert urgently — often after losing valuable time and revenue.
