 * Hi there,
 * Thanks for sharing the details.
 * I’ve tried to replicate the issue on my test site using the same plugin version,
   but I’m not able to reproduce the warning — everything is appearing as expected
   on my end.
 * Since the issue isn’t occurring consistently across all setups, it might be related
   to specific settings, theme or plugin conflicts, or a particular server environment.
 * To assist you further, I’d like to understand your site properly. Please share
   with us the necessary information below for us to investigate the issue further:
    - **System Status Report** which you can find via WooCommerce > Status
    - **Fatal error logs** (if any) under WooCommerce > Status > Logs.
 * Please use [https://pastebin.com/](https://pastebin.com/) or [https://gist.github.com/](https://gist.github.com/)
   and share a link to that paste in reply here. Once we have more information, 
   we’ll be able to assist you further.

 * Hello
 * Yes, it is true what you say, but the previous version is working fine with my
   setup.

 * Hi there!
 * Thank you for sharing the System Status Report. I’ve reviewed it, and everything
   appears to be in order. However, I noticed that you have quite a few plugins 
   installed on your site. It’s possible that one of them may be conflicting with
   the latest version of the Stripe Gateway plugin. Also, it seems like you have
   downgraded the Stripe Gateway plugin to an older version.
 * To determine whether a plugin conflict is causing the issue, please create a 
   staging site. You can use the following plugin to easily set one up:
   🔗 [https://wordpress.org/plugins/wp-staging/](https://wordpress.org/plugins/wp-staging/)
 * Once the staging site is ready, please follow the instructions in this guide 
   to perform a proper conflict test:

 * Hi [@negapo](https://wordpress.org/support/users/negapo/),
 * I understand how frustrating it is to run into that warning, especially when 
   it appears after an update and disrupts your checkout experience. Thank you for
   jumping in to share what you’re seeing.
 * That said, since each site setup can be quite different, including themes, plugin
   combinations, and server environments, it’s best we look into your case individually.
   Per the forum best practices and guidelines, we recommend creating a new thread
   so we can properly investigate and assist with your specific setup: [https://wordpress.org/support/forum-user-guide/faq/#:~:text=get%20individual%20help.-,I%20have%20the%20same%20problem,-!%20Can%20I%20just](https://wordpress.org/support/forum-user-guide/faq/#:~:text=get%20individual%20help.-,I%20have%20the%20same%20problem,-!%20Can%20I%20just).
