Contact Form not working

Hi!

I’m not sure if this has been posted elsewhere (I tried looking) but I’m having an issue with my contact form – no matter what I do, I’m not receiving messages from my contact form or concerning comments.

I’ve tried multiple contact forms – none work.
I’ve emailed BlueHost – the error is not from them as it is showing the email is leaving my site
I’ve emailed my theme developer – it is not an error from their side

It seems the issue began when I updated WP to version 4.6.
Here is my site link:

Also, I have not installed any new plugins that could cause the issue – I was receiving messages up until I updated and now suddenly, nothing!

Thank you!
