Hi,
We can see that you have the console open and it does not display any error.
The "network" tab would be interesting in order to see the ajax call and see what the server replied (the HTTP code and the content).
With this information, we will be able to understand the issue and know how to fix it.

By the way, do not send me private message, use the "contact us" form instead.
