Support » Plugin: Extended Post Status » nginx error 500

  • Hi,

    I’ve migrated my site from LAMP to NGINX server, now if I activate the plugin and I try to edit any kind of post (product, post, page) I get blank page and ERROR 500.

    It happen only on NGINX not on the old LAMP.
    It happen also with no plugin installed/activated but just “extended-post-status” and WooCommerce with WordPress default theme.

    This is the log I got:
    2020/06/03 19:31:11 [error] 994#994: *417 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Call to undefined method WP_Screen::is_block_editor() in /sites/

    Thanks in advance to your help! πŸ˜‰

    Hi @monkey-theatre

    I just setup a nginx on ubuntu 18 and installed the default mysql and php (7.2) setup and can’t reproduce the problem.

    The called class “WP_Screen” is a core class, which should always be callable.

    Could you provide the content of phpinfo()?

    Greetings Felix

    Hi Felix,

    I could do that with a WP plugin.
    Hope this is readable. πŸ™‚

    Hi @monkey-theatre

    my setup is nearly exactly the same as yours and I’m not able to reproduce the error πŸ™

    But the error message is interesting. Do you use nginx as reverse proxy and php is still deliveread via FastCGI – Apache? Maybe you could try to use FPM for PHP, just to have a quickfix.

    Greetings Felix
