Minimum requirements to install the POP plugin

Goal

Check that your WordPress environment meets the minimum requirements before installing POP.

Requirements declared by the plugin

These are the values declared in the plugin package (header and readme.txt). WooCommerce’s HPOS (High-Performance Order Storage) is supported starting from WooCommerce 9.x. To reliably use all current features (setup wizard, Integrations tab, XML/PDF generation via the cloud API), we still recommend an up-to-date environment — WordPress 6.x and WooCommerce 9.x or higher — consistent with what your hosting already requires for security reasons.

How to check the installed versions

• WordPress: wp-admin > About WordPress (or at the bottom of any wp-admin screen).
• WooCommerce: WooCommerce > Status (tab “Status”), “WordPress environment” section.
• PHP: on the same WooCommerce > Status screen, “Server environment” section.

Verify

If the installed versions are equal to or higher than the minimums in the table, you can proceed with first-installation.

Common errors

• The plugin doesn’t appear among the ones you can activate / fatal error on activation — check the PHP version: very old environments (PHP < 7.4) may behave differently in some areas of the plugin that depend on more recent autoloading features.
• Some settings don’t appear (Integrations tab, wizard) — make sure WooCommerce is active and up to date: the plugin registers its hooks against WooCommerce at init.
• Before updating WordPress/WooCommerce to a major version — test in a staging environment: see update-plugin for the procedure to update only the POP plugin.
