no more e-mail confirmation of a new order

I use wordpress 4.9.5 with theme Dazzling.
Woocommerce version: 3.3.4

my url: agoshop.at

Since today I will not get any e-mail confirmation when a customer will do a new order. The customer will get an e-mail of his order. Yesterday everything works fine.

Hope somebody can help me.
kindly regards

Hi there

Hope you are having a good day and thank you for your question
Sorry but this problem is not related with the theme, if you have a problem with Woocommerce shop plugin then you have to contact their support, also i suggest you research your question in the internet because your question seems generic and maybe you can find answers much faster than opening a new ticket with Woocommerce

Thanks!
