Our application page does not load for certain users

We have an application page integrated into our website, and we have received several complaints that it is not loading / the application form does not insert into our website. 

I would appreciate having a customer support team member talk me through it on the phone if possible! This is my second time submitting a help request for this issue.

We have responded to your thread already. Please check my colleague's reply there. Here's the thread: https://www.jotform.com/answers/1732110-Why-can-t-some-people-see-my-form.
