    I keep on getting the mmessage 'Invalid request. Please try again.'

    This is the code I'm using:

    [mb_frontend_form id='paying-member-input-details' object_id='{{ post.ID }}' post_fields='' ajax='true' submit_button='Save']

    Any idea what may be causing this?

    Hello Eddy,

    Thanks for reaching out.

    I don't see any issues with the frontend form shortcode. Do you use any custom code that affects the mbfs_key of the form? Please try to deactivate all plugins except Meta Box plugins, switch to a WordPress theme and recheck the form submission.

    I made a fresh copy in staging, and there it's working nicely.
    I'm checking with the support team of my hosting provider. Hoepfully they can help solve it, or at least help understanding what / where to investigate. I may get back here.

    Hi,

    I got a response from the support unit of my hosting provider.

    After further investigation, I found that the issue is with the Metabox plugin, which is not compatible with the Object Caching feature. This explains why it functions correctly on the staging site, where Object Caching is not active.
    Please note that disabling Object Cache is not recommended, as it can significantly impact server performance. I suggest reaching out to the developers of the Metabox plugin to inform them of this issue, as it seems their plugin is not designed to be compatible with the server’s Object Caching.

    Can you pls have this checked and see if this can be resolved?
    Thanks a lot, regards,
    Eddy

    Hello Eddy,

    Thanks for the details.

    Can you please ask them to share more details about the compatibility with Object Cache? I will also inform the development team to research this and let you know if I have more information.

    Peter, my sites are hosted at WPMUDev, they have documentation about it here: https://wpmudev.com/docs/hosting/tools-features/#object-cache

    Do you want me to check with them for a way that your development team can discuss this further with them?
    As I don't think that me staying in the middle will be very practical.
    Let me know.

    Hello,

    Our development team has checked the issue and didn't find the compatibility issue with Object Cache. Technically, we are using the transient to save the form key mbfs_key as I mentioned above. And the transient will be saved to the Object Cache by WordPress.
    The issue happens when you submit the form, is somehow the function in the background doesn't get the form key from the transient. See these screenshots https://imgur.com/a/vXbKafy

    I've tested again with Redis Object Cache and not see the same issue. I think you can share this info with the WPML support and see if they can help you monitor the transient value on your site.

    You're right.
    As the frontend submission form is loaded within a popup window and I have only the memberid (which is the page title) a used a get_posts with just 1 post.
    I've changed it: upon clicking the pencil icon I store the post-id in a user meta field which I read in the View (from where the frontend submission is called).
    Now it saves properly.

    Now just another question arises: I've set the redirect url, but it doesn't reload the entire page. Ajax=false.
    How can I reload the entire page, so that the saved changes become visible right after?

    Hello Eddy,

    If you are using some custom code to show the frontend form in a popup window, the PHP redirect function won't work properly. So you can use the JavaScript code to reload the page. For example:

    window.location.reload();

    I would expect that the action rwmb_frontend_after_save_post should be used, but it's not firing.

    This is my reload-after-save-metabox.js:

    jQuery(document).ready(function($) {
    // This fires when MB Frontend Form finishes saving
    $(document).on('mb_frontend_after_save', function(e, data) {
        console.log("✅ MB form saved, reloading now...", data);
        window.location.reload();
    });
});

    I'm a real beginner with JavaScript. Can you point me in the right direction?

    Typo, but result is the same...

    jQuery(document).ready(function($) {
    // This fires when MB Frontend Form finishes saving
    $(document).on('rwmb_frontend_after_save', function(e, data) {
        console.log("✅ MB form saved, reloading now...", data);
        window.location.reload();
    });
});

    Hello,

    There isn't a JavaScript event name rwmb_frontend_after_save like that. If you want to use the WordPress hook with PHP code, you can use the hook rwmb_frontend_after_save_post
    Following the documentation https://docs.metabox.io/extensions/mb-frontend-submission/#post-actions

    If you are not familiar with JS code, we offer a customization service with an extra fee. Please contact us here to get more details https://metabox.io/contact/

    Peter, I don't want to use the wordpress hook.
    I follow your recommendation to use the JavaScript code to reload the page. What I want to know is the trigger that should fire the Javascript. If it's not this hook, then what is it?
    How can I reload the full page after successful safe?
