When unpkg Fails, PrestaShop Suffers

Since Friday evening (03/14/2025), some PrestaShop users, particularly those using version 8 Classic Edition, have experienced difficulties accessing their management interface.

This issue stems from the CDN used in several modules developed by PrestaShop for this edition. While it affects other versions, the impact is less severe as it involves less critical modules, potentially causing slowdowns without complete blockage.

Indeed, the unpkg CDN used by these modules has been malfunctioning since last night, preventing the loading of static CSS and JS files.

Why is Version 8 Classic Edition More Affected?

This version introduces a new back-office design through the ps_edition_basic module, which is responsible for presenting the entire PrestaShop back-office. The unavailability of several CSS and JS files disrupts page display or severely degrades the design, rendering navigation impossible.
