Some users are not able to see embedded form.

We have embeded our form into our website ( http://ymg.odtuvt.org.tr/ymg-plus-kayit/ ) and while some users are able to see form, others are not able. It is an urgent situation. Thanks if you can help.

Unfortunately, I can't find any embedded Jotform form on the page you shared. As checked, it's a Google Form:
