Yoast plugin breaks website

Hi @daanw85,

Thanks for reaching out.

In order to troubleshoot the issue, could you please check the following steps?

1. Can you confirm your server has all the right requirements? This guide explains more: https://yoast.com/help/plugin-requirements/

2. Can you confirm that all the Yoast & non-Yoast plugins and themes are updated to the latest version? In most cases, these steps resolve this issue, but if the issue remains:

3. Can you check for any PHP errors related to Yoast SEO in your email or in the server error logs? You can find the errors yourself by enabling WP_DEBUG in your wp-config.php file. Once you have enabled it, reproduce the error, and check for any Yoast SEO errors in the debug.log file. You can also check with your web host to see if there’s a related error in your PHP error logs.

4. 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 except Polylang and switch to a standard theme like Twenty Twenty.

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

If you feel uncomfortable doing this yourself or if this does not solve your issue, our Yoast SEO Premium plugin comes with one year of (technical) support.

(google translated the above: Function WP_Service_Worker_Caching_Routes::register was called incorrectly. The plugin configuration key is out of date. Define Workbox plugin configuration at the top level. Read Debugging in WordPress for more information. (This post was added in version 0.6.)

4: I’ve tried to just run Yoast and Polylang and the problem only occurs then.

Thanks for helping out. I hope there’s an easy fix.

Specific URL i tested was this one btw: https://www.integron.nl/inzicht/

Hi, forgot to set the status to ‘not resolved’ again, so I guess it’s has been quiet because of that.

The issue is still not resolved. Can anyone be of any help with the above debug info?

Help will be greatly appriciated :).
