FastCGI CDiscount

Some hosts run under FastCGI, others under mod_php. For PrestaShop, the usual recommendation is mod_php.

Our modules are diagnosed against mod_php only — the PrestaShop standard.

Our product pages state that our solutions target hosting compatible with PrestaShop’s recommendations:

If you were sent to this page, your hosting uses FastCGI. We cannot support FastCGI-specific issues (tools and expertise stop at our modules, not hosting setups and their limits).

Under FastCGI, some important php.ini settings may be ignored because FastCGI config takes precedence. Example: FcgidBusyTimeout (default 300) overrides max_execution_time. That often interrupts long scripts and shows up as an “ajax error”.

Pass these PrestaShop PHP guidelines to your host/tech provider:

They should also review FastCGI parameters (not only PHP):

Those PHP.ini tips date from 2013 — use the higher suggested values, or raise them as needed for your catalog size.

We do not provide meaningful technical support for anomalies on FastCGI. If you hit problems in that environment, switch to mod_php so you can get support under our usual conditions: Support CDiscount.
