Uncaught ReferenceError: yoastWebpackJsonp is not defined

Idem !

I have the same problem. How to fix this ASAP?

Unfortunately, we are unable to replicate the issue from our end. Can you please confirm if you are using the latest Yoast SEO 7.9, WordPress 4.9.8 and the latest version of your theme? What triggers the error? Does the issue happen even when using the default WP theme?

@jerparx You likely have a Git hub versioning push to svn issue.
Your trunk on git hub does not match svn. Also your RC1 branch was partial merged with 7.9X which means your internally running code that is not available to the worls thru the WordPress update feature.

ya might want to merge tickets all recent ones are related to this.

The problem is solved by disabling the Gutenberg.

Disabling Gutenberg does not work for me, still blank meta title and description box

Hey guys,

Thank you for reporting this issue, we’re sorry for the troubles. Upon further investigation, we found that this issue happens when both Gutenberg and Classic Editor plugins are active. When deactivating either of the 2 plugins, Yoast SEO seems to be working as expected.

We have opened a GitHub issue and sent it to our development team, they will provide a solution as soon as possible. In the meantime, you can follow the progress or let us know if you have any other information here.

Please update to the latest version of Yoast SEO for WordPress v8.0 and this should be fixed accordingly. Setting to resolved.

Same problem here.
