In addition to that, I'd also like your help enabling the WordPress debug mode.
To do so, please add the following code in wp-config.php file of your site:
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );
Please check following links to read more about debugging with WordPress.
After doing that please try to reproduce the issue again, then check if you can find a file debug.log inside the wp-content folder. Open it and send us the last lines of log here in this ticket.
