Endless site loading, form submission not working?

Question

AJAX

Hello! Please tell me what to do, no strength.
I made a site on my test hosting, everything works, the page does not load for a long time, mail reaches my gmail instantly. ( https://furcifer21.000webhostapp.com)
I reupload everything to the working hosting - there is a constant load, a lot of errors and mail does not arrive ( http://turvgruzia.rf)
what could it be and how to fix it, tell me please?

Answer 1

well, so read what you write in the console there.
You have hundreds of hits on YouTube there, so figure out the settings.
