I cannot update modules, why?

An update can fail for several reasons: Marketplace connection, download rights, compatibility or an error during the operation. An outdated or misconfigured ps_mbo module is one possible cause; failure alone does not establish the diagnosis.

For a PrestaShop Marketplace purchase:

• On PrestaShop 1.7.7 and later, check that PrestaShop Marketplace in your Back Office (ps_mbo) and PrestaShop Account are installed, correctly configured and linked to the account used for the purchase. Check the affected module’s Business Care rights.
• Use a compatible ps_mbo version: its official documentation distinguishes 3.x for PrestaShop 1.7.7/1.7.8, 4.x for PrestaShop 8 and 5.x for PrestaShop 9. Do not simply select the highest version number.
• Before PrestaShop 1.7.7, the old native Marketplace connection no longer works: download the compatible ZIP from your Marketplace account and upload it in the Module Manager.

Do not uninstall the business module to unblock its update: this may delete its settings or data. If an error occurs, send support the exact message and the versions of PrestaShop, PHP, the affected module and ps_mbo.

For a direct purchase from the publisher, use the ZIP provided under your purchase rights. Marketplace rules do not apply to that download.
