  • Hey @fruchtfliege,

    I just stumbled upon what appears to be the same (or at least very similar) issue and after a lot of troubleshooting, I discovered that since PHP error reporting was on, there was a PHP Warning about missing arguments and the HTML for that warning was being returned instead of valid JSON. After I set the following in the wp-config.php file, my forms started submitting normally again.

    define('WP_DEBUG', false);
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );

    It may or may not be a solution to your specific issue but since I consistently found this post in my trip through Google searches, I figured it couldn’t hurt to provide a potential solution.

    Hope it helps!
