Uncaught ReferenceError: wp is not defined

Hi there,

This is likely caused by a theme/ plugin conflict.

The best way to determine if the issue is being caused by a theme and/or plugin is to temporarily switch your theme to Storefront (https://woocommerce.com/products/storefront/?aff=10486&cid=1131038) and disable all plugins except for WooCommerce. Finally, test to see if the issue is resolved by checking to see if the error is gone.

To figure out which plugin is causing the problem, continue to the next step – reactivate your other plugins one by one, testing after each, until you find the one causing conflict.

Here’s a more extensive explanation in our docs: https://docs.woocommerce.com/document/how-to-test-for-conflicts/

Meks Quick Plugin Disabler is a plugin you can install which will remember what plugins you currently have active so it’s easy to switch them back on. Link: https://www.ads-software.com/plugins/meks-quick-plugin-disabler/

You can clone your site to a staging environment and perform tests without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free WP Staging plugin. Link: https://www.ads-software.com/plugins/wp-staging/

Thank you. It was the ‘Load Javascript deferred’ setting in WP Rocket. I’ve turned it off and now all is well.

I have the same problem using autoptimize.
When I turn off file aggregation the error doesn’t show up.

Excluding just the right files (try wp-includes/js) should help too bonovski.

Thanks for the suggestion, this does work but adds 12 additional network requests.

Did you manage to find out the exact file(s) to exlude apart from wp-includes/js?

Thank you for this post it helped me trace down the issue ??

found it, with some luck but glad I could share the file that solved it for me:
wp-includes/js/dist/i18n.min.js
For me excluding that solved it all round without excluding all in the /wp-includes/js folder

For me it was the Async Javascript plugin.

Hi there, having an error which seems similar to yours but havn′t found a solution yet.

As I switched over from divi builder back to storefront the error was not shown anymore but of course I want to keep the divi builder as a great tool.

Is there any chance to solve this issue?
THX in Advance

Hello, for those having trouble with Autoptimize and/or Async JavaScript, the solution for me was to set these folders/files on exclude field of both plugins:

wp-includes/js/dist/, wp-includes/js/tinymce/, js/jquery/jquery.js, js/jquery/jquery.min.js

All errors gone.

I hope it helps you all.
