    Dear Concern,

I am not able to access my Yoast SEO settings on Edit Page. I am facing javascript error in console.

The errors are below:

Uncaught TypeError: Cannot read properties of undefined (reading 'SlotFillProvider')

at classic-editor.js?ver=ff2a08cf309522fdc93ffd19f7311587:227:5806

at window.yoast.initEditorIntegration (classic-editor.js?ver=ff2a08cf309522fdc93ffd19f7311587:227:6127)

at HTMLDocument.<anonymous> (post-edit.js?ver=7a02bee21ada1b649f35fc0b142d26fa:11:3042)

I already disable another plugins and themes but still facing same issue.

Wordpress Version : 6.2

Yoast SEO Version : 20.5

Yoast SEO Premium : 20.5

Please let me know if you need anything from my side.

    Hi @yogeshbarot15

    Thanks for using Yoast SEO plugin. We understand that you are noticing a JavaScript error like Uncaught TypeError: Cannot read properties of undefined (reading ‘SlotFillProvider’) when trying to edit the page.

    Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty-Two.

    Please test this on your development or staging site if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.

    If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts.

    Hello,

    We have this exact same problem on several admin pages. Console output on /wp-admin/admin.php?page=wpseo_page_settings:

    w-settings.js?ver=1d99649884583482e41aa4c53c695620-b-modified-1688131811:260 Uncaught TypeError: Cannot read properties of undefined (reading 'SlotFillProvider')
    at HTMLDocument. (new-settings.js?ver=1d99649884583482e41aa4c53c695620-b-modified-1688131811:260:7015)
    (anonymous) @ new-settings.js?ver=1d99649884583482e41aa4c53c695620-b-modified-1688131811:260

    Firefox generates a quite similar error:

    Uncaught TypeError: n is undefined
    new-settings.js:260:6989

    We tried Health Check & Troubleshooting plugin, with the Twenty Twenty-Two theme, just activating Yoast SEO and Yoast SEO Premium plugins (we do have a license). Both Version 20.10.

    Thank you very much for you help !
