Support » Fixing WordPress » Problem with loading edit page for posts/pages

  • Hi
    I use WordPress 5.0.3 and I have a bad problem with loading the new/edit page for posts (and pages). When WordPress try to load edit page for posts (or pages), it fails and I receive following error in the web console of Firefox browser:

    Unhandled promise rejection Error: “[object Object]”
    Redux

    path_to_localhost/wordpress5/wp-includes/js/dist/vendor/wp-polyfill.min.js?ver=7.0.0:2
    path_to_localhost/wordpress5/wp-includes/js/dist/vendor/wp-polyfill.min.js?ver=7.0.0:2
    path_to_localhost/wordpress5/wp-includes/js/dist/vendor/wp-polyfill.min.js?ver=7.0.0:1

    I searched for a good solution, but I did not find it. Please guide me.

    Thanks

  • Does the issue still happen with all plugins disabled and a default theme (Twenty Nineteen) activated?

    i can’t replicate above issue in fresh install WordPress 5.1

    @mukesh27 Yes, I disabled all plugins but this problem has not been resolved. I don’t like to update WordPress completely, so if it is possible, please guide me to replace new necessary files with old files just for resolving this problem. Thank you.

    @mostafadeveloper, Please refer this https://codex.wordpress.org/Upgrading_WordPress article to update WordPress.

    @mukesh27 I updated WordPress, but the problem has not been resolve. I still receive same error in web console and the edit page is not loaded. Do you know a real solution?

    i had the same error:

    Error:
    A) Unhandled promise rejection
    B) taxonomies?per_page=100&context=edit&_locale=user
    C) wp/v2/users/?who=authors&per_page=100&_locale=user
    D) invalid_json

    This kind of error, usually it’s a plugin error:
    1- Disable all plugins
    2- Try to generate or reproduce the error.
    3- If resolve you must activate 1 plugin at the time and repeat the step 2.

    In my case i got the error when the “JWT Authentication for WP-API” VersiĆ³n 1.2.4 plugin is activated
