Reinstallation

When you reinstall the plugin, the plugin takes care of most of its configurations and functions except for the items listed below. We recommend that you follow the steps here to make sure that when you reinstall the plugin, it won’t pick up settings from a previous installation. Order status
  • The plugin keeps the Awaiting Sezzle Payment order status because existing orders might still use them. If you would also like to remove these statuses, first make sure that these are no longer in use.
  • To check if the status is in use:
    1. Go to the Orders page in your Prestashop admin panel
    2. Filter the orders for the Awaiting Sezzle Payment order status
    3. If there are any, move them to another status that you would like to use
      • When there are no more orders using this status, you can delete the status from your order status list
Configurations The plugin keeps the AWAITING_SEZZLE_PAYMENT configuration fields in your database in case there are still orders in your system with the corresponding statuses. If you have already removed the status, you can also remove these leftover configurations.
