Spinning wheel on Direct Message

Hi,
This seems like a plugin conflict. Kindly disable all other plugins except WooCommerce and WCFM plugins. After that you can enable rest of the plugins one by one to find out the cause.
one query – Did you disabled rich editor option for your vendors, from Capability settings?
Let me know how it goes.
Thanks!

Hi,
The WP rich editor library(tinymce) some how gets initiated here. It shouldn’t be, as you have disabled that feature. I believe there might be some other plugin producing this conflict.
You can try using the following hack to bypass this. This code is untested as I couldn’t replicate the issue on my side, but it should work.

add_action('wcfm_main_contentainer_after', function() {
    $rich_editor = apply_filters( 'wcfm_is_allow_rich_editor', 'rich_editor' );
    $wpeditor = apply_filters( 'wcfm_is_allow_product_wpeditor', 'wpeditor' );
    if( ! $wpeditor || ! $rich_editor ) {
     ?>
    <script>
        setTimeout(function(){
            window.tinymce = void 0;
        },0);
    </script>
    <?php
    }
});

Add this code to your child theme’s functions.php
In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/
Let me know how this goes.
Thanks!
