We have a CORS issue with Safari, and Chrome in Incognito.
Solution 1 : alternative URL
Before I am able to fix is properly for wolfery.com, you can use this URL instead:
Unfortunately, since the browser sees it as a different domain, you will not see old logs.
Solution 2: allow cross-site tracking
As @Tlancaalek pointed out in this post, you can solve it by disabling “Prevent Cross-Site Tracking”:
On iOS, this is in Settings > Safari. Look under the Privacy & Security pane, and the very first option should be “Prevent Cross-Site Tracking.”. Turn that off.
This is the option to use (for now) to also have your logs available.
