Error on “Add to Cart” button, 404 error
The requested URL /bigcommerce/cart/42 was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
In WordPress, go to Settings → Permalinks. Scroll to the bottom of the page and click Save. This resets the site’s redirects properly.
PHP getenv() Errors
When in use the plugin floods the error log with the following:
PHP message: PHP Warning: getenv() expects exactly 1 parameter, 2 given in wp-content/plugins/bigcommerce-for-wordpress-0.11.1/bigcommerce.php on line 58
You can expect to see that error if you’re on PHP version 5.4 or lower (the plugin requires 5.6+).
