Plugin Update Failed http 500

  • Unknown's avatar

    hi
    I swear I created a post on this topic but cannot find it.
    Since WP version 5, I have this http POST 500 for every plugin update, even though update works fine every time.
    This creates a message under the plugin, and interrupts updating of all plugins with a click. Example:
    Update Failed: {"success":true,"data":{"update":"plugin","slug":"advanced-iframe","oldVersion":"Version 3.0","newVersion":"Version 2019.7","plugin":"advanced-iframe/advanced-iframe.php","pluginName":"Advanced iframe"}}

    I don’t understand the cause of this error 500 other than it’s linked to WP version 5 and beyond. My folders ACLs are correct as I use WP all in one security to check it.

    Absolutely everything else works. Just plugin update handled by wp-admin/admin-ajax.php returns error 500. All the response headers are returned correctly, and the JSON response returns true.

    Maybe one of the core php class has not updated correctly? Where should I look? Frontend is nginx and I never changed the website definition. The staging site has the same issue.

    any idea is welcome :)
