Forms Failing to load entirely on Safari 16.5 (MacOS Ventura)

The CMS Questions
1

I created multiple forms closely following the official kirby docs ( Contact form | Kirby CMS )
These work well on most devices. But on slightly older MacOS/Safari versions it doesn’t work at all. Showing a full screen error ‘a problem repeatedly occurred’.

My client is an apple hardware reseller so wide compatibility with apple devices is a priority.

I am on the newest kirby version 5.11 (before I was on 5.0, issue persists on both versions).

Is this a known issue? (I searched a bit and wasnt able to find anything)
Are there any other sites online with kirby cms forms that I could test on my devices to isolate whether its truly kirby or some frontend css problem for example.

Its strange that the error immediatly occurs upon loading and not perhaps later when trying to submit the form.

Any and all help regarding this would be much appreciated.

Base on my own searches, this seems to be a broader Safari issue but specific to individual devices. All reported occurrences were never about a specific site or their code but were fixed with something in regard to the device. Some things where people reported that it fixed their problem:

  • Settings > Safari > Advanced > Remove All Website Data
  • Restarting the device
  • Disabling safari extension to find the one causing the problem

Maybe something of these helps you too.
