Quick answer

A critical error after updating WooCommerce is usually a plugin, theme or PHP incompatibility. Turn on the debug log to see the cause, disable plugins by renaming folders, or roll back.

Most likely fix: Back up and read the error

How to fix it

Try these in order — the most common fix is first.

  1. 1. Back up and read the error

    1. Back up files and database
    2. Set WP_DEBUG and WP_DEBUG_LOG to true and WP_DEBUG_DISPLAY to false in wp-config.php
    3. Read wp-content/debug.log and WooCommerce > Status > Logs for fatal errors
    Did this fix it?
  2. 2. Get back into admin

    1. Via FTP or file manager, rename the suspect plugin folder in /wp-content/plugins/ to deactivate it
    2. Rename WooCommerce's folder too if needed, then rename back
    Did this fix it?
  3. 3. Isolate the culprit

    1. Disable all plugins except WooCommerce
    2. Switch to Storefront or a default theme
    3. Re-enable one by one
    Did this fix it?
  4. 4. Roll back

    1. Use WP Rollback or upload the previous version
    2. Wait for the extension author to release a compatible update
    3. Clear all caches and re-save Settings > Permalinks
