Support » Plugin: Yoast SEO » Conflict With WP 5.0.3 and Classic Editor

  • Resolved sc456a


    We’ve noticed that sites with WP 5.0.3 and the Classic Editor plugin are no longer able to add/edit pages/posts when Yoast SEO 9.4 is installed. If Classic Editor or Yoast is disabled, things work normally. All three running at their latest versions is the only way to replicate the bug. Please advise.

    We are not able to reproduce any issues on our sites with Yoast SEO 9.4, WordPress 5.0.3 and the Classic Editor plugin 1.3.

    That sounds like a plugin or theme conflict. Can you try and gather as much information for us as possible? Please perform the following:
    1. Check for JavaScript errors with your console. If you see any errors, can you please send us a screenshot?
    2. Check for conflicts.

    If you find any JavaScript errors related to Yoast SEO or if there is a conflict with a plugin or a theme, you can create a new GitHub issue for our developers. Please report the issue to a third party developer as well.

    If you didn’t find any conflicts or errors, we think the issue is specific to your site. We’d need to investigate further but are unable to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.

    I’ll follow up with the JS errors I’m seeing via Email.

    For me, it was a conflict between Yoast and an older version of the Toolset Types plugin.

    Glad to know you were able to figure out the conflicting plugin.
    Does updating Toolset Types to its latest version resolve your issue?
    If the issue persists, please report the issue to the developer of the 3rd party plugin.
