Button new window and WhatsApp Button

i had some updates yesterday and now problems - it blew everything up in java script yesterday.

I use the theme Sydney

I wanted to add a WhatsApp button to the Contact page yesterday so that a customer can send me a Whatsapp directly (I had tried several plugins for that) but then noticed that this probably does not support the theme Sydney?

The button with me “Shop” doesn’t work anymore in a new window since yesterday. It doesn’t accept code snippets either and the link with target="_blank" doesn’t work either.
