I am getting this error when I changed my woocommerce-2.3.13 version to woocommerce-2.4.6:
WooCommerce: SyntaxError: Unexpected token <
As per my knowledge, when i am adding script tag(< script>) on php file, the open script tag < giving errors, it means it is not reading the script tag.
I added my plugin(on php file) to connect checkout process with payment gateway to redirect to get bank list page. This error is coming when I try to redirect using JavaScript. Redirect function header("location:$url") is not working so i am using JavaScript.
?>
<script type='text/javascript'>
window.location.href="<?php echo $url; ?>";
</script >
<?
I tried
define('WP_DEBUG', false);error_reporting(0);@ini_set('display_errors', 0);
but I am getting the same errors.
When the WooCommerce checkout is processed it requires that gateways return an array (which is then converted into JSON) telling the checkout whether or not it was successful. Itâs been this way since v1.
In 2.4+ this was made more strict in that the response must be valid JSON. Anything else in the response (such as HTML, notices or whitespace) will invalidate this JSON and you may see an error along the lines of:
See a way to debug it in this blog post https://mikejolley.com/2015/11/12/debugging-unexpected-token-in-woocommerce-2-4/
I followed all the instructions on that blog post, disabled all the plug-ins, and it turned out that the JSON response was sending back an error instead of correctly formatted JSON. My response was:
In my case, it was a problem with WooCommerce PayPal Pro payment gateway and WooCommerce Product Vendors because cURL was not installed by default on my DigitalOcean server. With WooCommerce Product Vendors, every time a customer places an order, the vendor gets paid commission with PayPal Mass Payments. In order for PayPal Mass Payment to work, you have to make sure that you enable Mass Payments on your PayPal account and to make sure the cURL is installed on your server.
As soon as I installed the cURL, it worked. Here is how to install cURL on DigitalOcean https://www.digitalocean.com/community/questions/curl-is-not-installed-in-your-php-installation
Hope this helps someone out there.
