Title: Deprecated Code Last modified: July 13, 2021 --- # Deprecated Code * Resolved [ldigregorio](https://wordpress.org/support/users/ldigregorio/) * (@ldigregorio) * [4 years, 11 months ago](https://wordpress.org/support/topic/deprecated-code-24/) * Hello, * With all the recent JS/JQuery changes to the WP core, yoast is showing deprecated code: * /wp-content/plugins/wordpress-seo/js/dist/post-edit-1650.js:1:101578): jQuery. unique is deprecated; use jQuery.uniqueSort * Can the code be updated before core 5.9 release please? If not, it could potentially break our site. Thank you * I was on vacation when the ticket was closed by Michale Tina, I didn’t have a chance to reply until I returned. Sorry I wasn’t able to get back to you sooner. Here are the answers to questions requested: 1. We are using WordPress 5.7.2 2. Yoast 16.5. At the time I wrote this, I think Yoast 16.6.1 has just come out and we were not yet scheduled to do all our upgrades. * 3. Our multi-site meets all the plugin requirements. * 4. Not sure how you would replicate the issue, as I found it by the jquery migrate plugin made by WordPress/automatic –specifically made to find deprecations so they can be fixed before core 5.9 release. Maybe install their plugin to find the issues with your plugin?

We plan to update this week so please give me time to do that before closing the ticket. I will get back to you after the update this week.

Can this be fixed please? * /wp-content/plugins/wordpress-seo/js/dist/api-client-1670.js:1:1262): jQuery. isFunction() is deprecated * [Md Mazedul Islam Khan](https://wordpress.org/support/users/mazedulislamkhan/) * (@mazedulislamkhan) * [4 years, 11 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14658251) * Thanks for following up with us [@ldigregorio](https://wordpress.org/support/users/ldigregorio/). Can you please confirm where exactly do you see the relevant `jQuery.isFunction()` is deprecated notice? Is there a specific page where we can take a look at to reproduce the notice? * We look forward to hearing from you. * Thread Starter [ldigregorio](https://wordpress.org/support/users/ldigregorio/) * (@ldigregorio) * [4 years, 11 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14660053) * Hello Mazedul, * Thank you for getting back to me. I don’t think looking at the page is going to help. The jquery migrate helper plugin actually found this issue. This plugin was created by Automatic to find these issues so they can be fixed before the backward compatibility for jquery is stripped from core in WP 5.9. Maybe there would be more mileage from looking at the code where the deprecation occurs. Can the deprecation be fixed? Send updated code so I can test it using the plugin again. Or, please install the plugin and test it there. Thank you * [Md Mazedul Islam Khan](https://wordpress.org/support/users/mazedulislamkhan/) * (@mazedulislamkhan) * [4 years, 11 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14662584) * Thanks for your confirmation, [@ldigregorio](https://wordpress.org/support/users/ldigregorio/). We could definitely try upgrading from the deprecated part of our code. In this case, we recommend you please submit a proper bug report directly at our [GitHub development repository](https://github.com/yoast/wordpress-seo/issues) so our development team can look into this further. * We actively track bug reports on our GitHub development repository rather than in the public forum. In this way, you’d be able to follow the progress of the relevant bug report as well. * [devnihil](https://wordpress.org/support/users/devnihil/) * (@devnihil) * [4 years, 10 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14685527) * We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue. * Thread Starter [ldigregorio](https://wordpress.org/support/users/ldigregorio/) * (@ldigregorio) * [4 years, 10 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14685778) * FYI…the issue was taken to GITHUB. After GITHUB, it was transferred to an internal queue to be fixed. So the issue is not really resolved, but moved to different lists. It still needs to be fixed before core 5.9 Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘Deprecated Code’ is closed to new replies. * ![](https://ps.w.org/wordpress-seo/assets/icon-256x256.gif?rev=3419908) * [Yoast SEO - Advanced SEO with real-time guidance and built-in AI](https://wordpress.org/plugins/wordpress-seo/) * [Frequently Asked Questions](https://wordpress.org/plugins/wordpress-seo/#faq) * [Support Threads](https://wordpress.org/support/plugin/wordpress-seo/) * [Active Topics](https://wordpress.org/support/plugin/wordpress-seo/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wordpress-seo/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wordpress-seo/reviews/) ## Tags * [deprecated code](https://wordpress.org/support/topic-tag/deprecated-code/) * [js](https://wordpress.org/support/topic-tag/js/) * 8 replies * 4 participants * Last reply from: [ldigregorio](https://wordpress.org/support/users/ldigregorio/) * Last activity: [4 years, 10 months ago](https://wordpress.org/support/topic/deprecated-code-24/#post-14685778) * Status: resolved
