Contribution Page not Submitting
When reproducing your experience, I see:

flbc.edu/:1 Uncaught SyntaxError: Unexpected token '&lt;'


Which is weird, since it seems to be loading your whole page as javascript.

It shows it on the initial page load as well as after submitting. And the province selector after selecting a country is also broken, that's probably a symptom of the same problem.

When I look at the html source of your page, I notice that it ends with:

&lt;script type='text/javascript' src='https://flbc.edu/wp-content/plugins/js_composer/assets/js/dist/js_composer_front.min.js'&gt;&lt;/script&gt;


That's bad - you're not getting your closing html or body tags output. 

Conclusion: I suspect you might be hitting some kind of server limit (your page has a lot of css/js loaded).

Do look at your server logs, there's probably a hint in there. I don't think it's CiviCRM-specific.
