WooCommerce might not be working for several reasons. Common issues include plugin conflicts, outdated versions of WooCommerce or WordPress, server misconfigurations, or conflicts with themes. Another issue could be insufficient server resources, such as low PHP memory limit or outdated PHP versions. Additionally, problems in the database, broken links, or corrupted files can cause WooCommerce to malfunction. It’s essential to check for plugin updates, ensure compatibility with the current WordPress version, clear any cache, and troubleshoot by disabling plugins or switching to the default theme. If the problem persists, contacting support or checking error logs is recommended.

To set up a payment gateway in WooCommerce, log in to WordPress admin and go to WooCommerce → Settings → Payments. You will see available gateways like Cash on Delivery, Bank Transfer, PayPal, Stripe/WooPayments, etc. Click the gateway you want, then Enable it and open Manage. Add required details like API keys, business email, or bank info. Save changes, then run a test checkout using a test product. Finally, confirm order emails and payment status update correctly.

WooPayments is WooCommerce’s built-in payments solution. It lets you accept debit/credit cards and express options like Apple Pay, Google Pay, and WooPay, and manage everything inside your WordPress dashboard. You can track transactions and payouts, issue refunds, and handle disputes without using a separate payment portal. In supported countries, it can also help you take in-person payments (like Tap to Pay on iPhone or card readers).
