FastCGI

Some hosting environments run under FastCGI, while others use mod_php.

The general recommendation for PrestaShop installations is mod_php.

Our modules perform all diagnostics based on environments running mod_php only, as this is the PrestaShop standard.

We remind you that our product listings clearly state that our solutions are designed to work on hosting providers compatible and recommended by PrestaShop.

Here is the official list:

If you were redirected to this page, it means that your hosting uses FastCGI.

In this case, we are unable to provide support for issues related to FastCGI environments — either due to lack of appropriate tools or because it falls outside our area of expertise.

Our expertise is strictly limited to the development and support of our modules, not to hosting configurations or their constraints.

Common Issues with FastCGI

One of the main problems is that some php.ini parameters do not apply under FastCGI, as FastCGI settings take precedence.

For example, the FcgidBusyTimeout parameter (default: 300) overrides max_execution_time.

This often leads to script interruptions during execution, resulting in “ajax error” issues.

You are likely encountering one of these limitations.

We recommend forwarding the following PrestaShop configuration guidelines to your technical provider:

They should also review the documentation related to FastCGI parameters, in addition to PHP parameters:

Recommendations

Please note that these parameters date back to 2013, so you can safely increase the suggested values according to our recommendations.

We do not provide technical support for anomalies encountered in FastCGI environments.

If you experience issues under FastCGI, we strongly recommend switching to mod_php hosting so that you can receive full support from us.
