Wordpress-seo: "Loading help center." when Classic Editor plugin is active

[gran1887]

• [x] I've read and understood the contribution guidelines.
• [x] I've searched for any related issues and avoided creating a duplicate issue.

Please give us a description of what happened.

Noticed "Loading help center." and did a search to see if other also experienced this. Most cases seemed to be related to plugin conflict, so deactivated all and turned them back on one by one. Classic Editor plugin was the one where the issue manifests itself.

Please describe what you expected to happen and why.

see above

How can we reproduce this behavior?

1. install and activate Gutenberg
2. install and activate Classic Editor
3. go to any of the Yoast SEO Settings pages

Technical info

• WordPress version: 4.9.7-alpha-43316
• Yoast SEO version: 7.6.1
• Relevant plugins in case of a bug: Classic Editor
  
• Tested with theme: Twenty Seventeen

Thank you for reporting this issue. We've milestoned this issue for WordPress 5.0.

[gran1887]

It seems with every new version of Yoast this issue is getting worse, now it is no longer possible to add any SEO metadata when the Classic Editor plugin has been installed and activated. Please see the screenshot here:

With the Classic Editor plugin becoming more popular, I'm not sure if you want to wait til WP 5.0 lands to tackle this issue?

[CarolineGeven]

We're not waiting until WP 5.0 lands, @gran1887. We're actively developing for Gutenberg and WordPress 5.0. The milestone means that we will pick it up at least before WP 5.0 launches.

For developer: please investigate what is going on and discuss the suggested solution.

Also having this issue on WordPress 4.9.5 and 5.0.. running Yoast SEO 9.2.1.

Update: Upgrading to release/9.3 (beta) seems to have resolved the issue.

[zeusabn]

NO it is not resolved in 9.3

[Braunson]

@zeusabn 9.3 (beta) fixed the issue for _me_.

[crea8iveart]

I have this website → [https://proservicesdubai.com] and the theme use "WPBakery Page Builder" Plugin. This plugin is having an issue with YoastSEO Plugin.
When I disable this plugin, I am able to see the snippet.
