Applications are not ideal, as well as the code. The errors may occur when you don't expect them to, even in the most common and routine situations. They can be caused by the quality of the core code or due to the integration or upgrade. The versions of the collaborating applications might not match and result in the overall system failure. But the most common reason for the errors inside the application code is the human factor. It often happens when the website owners change the development team or perform upgrade by themselves.
Though we encourage our customers to learn more about programming and software configurations, we always warn them that some manipulations have to be left for the professionals as they can affect their Ecommerce business stability and security.
Due to our Service policy, we manage only the server, we don't manage the applications installed by the customer. Nevertheless, it's our concern to have the customer's business online and successfully growing with no interruption. That's why we decided to monitor the application performance regularly and inform the owners about anything we find that can slow down the website or cause critical errors. On the top of that, we are the most loyal CS-Cart fans and we've studied it throughout the years perfectly. We know the weak points that need precise monitoring.
