Reply To: Website keeps loading at Checkout page

You can not understand where the error comes from from the code at #470285? These error details where email to me from WordPress .
That started 2 days ago where I received a “weird” email that an account with the email info@breathclo.com was created and just after that I received an email from WordPress that there is an issue on the page with the following error:

That’s all I know.
However, looking at a product page in the backend I found out that all variations created for the attributes I have in each product have disappeared! And even when I add a new variation after I try to save it it still keeps loading just for ever..

I resend you at the extra info section the credentials for backend access.

Thanks in advance.
