Simon 5 is coming soon!
Simon version 5 is currently in beta testing. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.
Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and will be a paid upgrade from Simon 4 after the beta. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).
Re: HTTP 406 Errors
Interesting. What happens if you visit the same URL in your web browser? Perhaps try visiting it in Simon's Preview window, too. It might need authentication or cookies to be set.
Re: HTTP 406 Errors
Browsers render the site just fine. No authentications necessary; I'm getting the same error on all sites hosted on that box, which is a pretty plain-vanilla Fedora install.
The http reply above was cut and pasted from the preview window, except for replacing the less than sign with an html entity to make it render correctly.
If you want, email me and I'll shoot the real URL of the box to you.
Re: HTTP 406 Errors
BTW, I also get the same error if I address the index page directly.
Re: HTTP 406 Errors
Okay, send me the URL, and I'll investigate. You can use the contact form.
