Well, this is interesting. I tried it in Chrome, FF Developer (v. 75) and Safari on my older MBP running Mojave - no go on any of them. Error from the console in FF indicates a missing variable.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Not_definedA bunch of other warnings about deprecated things as well - this is NOT a recently designed page from the looks of it.
In Catalina, with the same version of Safari, it works. In FF (same version) it also works, after I allow the older TLS. In Chrome, it does zip, other than reload the page complete with the annoying popup.
There are warnings that the site is still using TLS 1.1 - and I checked the host, which is/was singlehop.com (it has been bought out by INAP) and sure enough, the host doesn't support TLS 1.3, which is not good since most browsers will mark the site as insecure, despite the presence of a current SSL certificate. All browsers stopped supporting the older SSL/transport protocol in March - which is why you can see the yellow warning triangle in the URL bar over the lock icon. I don't know why Safari still isn't flagging it though.
Anyway - this strikes me as a project someone has lost interest in. Site is not working properly, it's not secure, it's hosted by a host that has been gobbled up by another company (and seems to be sitting on some forgotten server somewhere), copyright notice on site says 2014-2017, blog doesn't work (database connection error)...
I would recommend that you NOT BUY this app!See:
