malwarebytes doesn’t like demo site

I tried to create a demo site from https://app.instawp.io/launch?t=essential-plugin-pro-demo&d=v1 (this may have been a redirect after I said to create the site)

But when I try to access the site, malware bytes says “Malwarebytes Guard blocked this page because it may contain malicious activity”

I have a screenshot, but it doesn’t look like this form allows files to be uploaded.
