    I have several forms on the website im working on at the moment. There is one very strange error: All the forms only work properly when i’m logged in the WP Backend. Trying to submit any of theses forms not beeing logged in simply does nothing.

    I have no idea what i can do – can anyone of the specialist here help me please?

    Regards
    Rainer

    It seems to be a problem with the RestAPI – there is an error 401 when trying to send:

    POST https://www.dentalmedizin-langweid.de/wp-json/contact-form-7/v1/contact-forms/1665/feedback 401
    send @ jquery.js?ver=1.12.4-wp:4
    ajax @ jquery.js?ver=1.12.4-wp:4
    wpcf7.submit @ scripts.js?ver=5.3:295
    (anonymous) @ scripts.js?ver=5.3:58
    dispatch @ jquery.js?ver=1.12.4-wp:3
    r.handle @ jquery.js?ver=1.12.4-wp:3

    @neubi What version of WordPress are you using? I started getting this same 401 error on my forms submitted by anon users when I upgraded my staging site to the WordPress 5.6 RC2 release.

    I should mention that this occurs even when I’ve disabled all other plugins and themes.

    Currently i use WordPress Version 5.5.3

    @neubi Ah, maybe your reason is different, does the error still occur when you submit the form in a private browsing session?

    unfortunatley it does.

    I think i did find the error. On all the affected websites i did find the following code on the functions.php of the Theme in use:

    add_filter( ‘rest_authentication_errors’, function( $result ) {
    if ( ! empty( $result ) ) {
    return $result;
    }
    if ( ! is_user_logged_in() ) {
    return new WP_Error( ‘401’, ‘not allowed.’, array(‘status’ => 401) );
    }
    return $result;
    });

    strangely enough all the funtions.php files in the affected site were changed on the same date – so I think an update of a plugin might habe been the reason.

    After commenting out that code all the forms are working porperly again.

    For me the failure was that I did this => Disable REST-API for all users except of admin

    So check if your rest-api is still ok for all users (can be deactivated by a security plugin or so , i did this myself , reverted it and all worked great again)
