Getting “ReferenceError: jQuery is not defined” – don’t know why!

The following code is trying to use jQuery before the jQuery library is loaded. Hard to say exactly where it is coming from, but it seems related to your form. If that is a custom form, maybe check in your theme’s header.php? It is definitely not being enqueued properly and so I would guess it might be hard-coded.

<script>jQuery(function(){jQuery('#input_38_7').attr('placeholder','First Name');jQuery('#input_38_6').attr('placeholder','Last Name');jQuery('#input_38_2').attr('placeholder','Email');jQuery('#input_38_3').attr('placeholder','Phone Number');});</script>

Maybe try using a better form plugin? Both Ninja Forms and Gravity forms are excellent.
