Checkout Page in Woocommerce 4.4.0

Hi Rahim, you seem to be having the same issue as myself and others on this thread:

https://www.ads-software.com/support/topic/js-critical-error-on-cart-page-shipping-calc/

I am trying to establish what common plugins we may be using: – I am using:

1. Elementor
2. Vouchers (standard Woocomerce option)
3. Serial numbers plugin
4. WooCommerce Stripe Gateway

Same issue here. I tried to deactivate all plugins. but it didnt worked out.

I also tried to switch themes with no results.

@rahimvaziri WordPress 5.5 removed a javascript file called jquery-migrate that some plugins which haven’t been udpated might still be relying on. Until they update, the workaround is to use the plugin Enable jQuery Migrate Helper to include the javascript files.

I’m not entirely sure this is the cause of the issue but since jQuery errors are referenced in the browser console screenshot your shared, it might be worth trying out.

If installing the plugin above does not solve the issue, I’d recommend trying a conflict test next:

You’ll want to temporarily switch your theme to Storefront. Then, disable all plugins on the site except for WooCommerce, and test for the issue.

If the issue is gone, you’ll then have to re-enable features one by one, while testing for the issue; until you find out which one is causing this behavior.

We recommend that these steps are taken on a staging site, which is a clone of your live site that you can modify without risking making any permanent damage to your live site. You can create it using a plugin like WP-Staging: https://www.ads-software.com/plugins/wp-staging/

Follow up, in my case Jquery migrate helper pluing did not resolve the issue. I found the error to be caused by 2 things, 1) the Remove Query Strings option in litespeed cache
page optimization setting and 2) Remove Query Strings From Static Resources plugin. Disabling 1 and 2 resolved the console error.

If anyone is looking for the solution that worked for me – Roll Back WOOCOMMERCE. There’s a critical error in 4.0.

1. Install this plugin: https://www.ads-software.com/plugins/wp-rollback/
2. Go to plugins and select “rollback” by WooCommerce.
3. Choose version before 4.x
Best of luck!

Version 4.4.1 was released a couple days ago to help with some of the conflicts that appeared with other plugins. I’d recommend updating as soon as possible. If the issues are not fixed, please still try the conflict test as described in my previous comment.

We haven’t heard back from you in a while, so I’m going to go ahead and mark this thread as resolved. If you have any other questions please feel free to start a new thread.
