Panel Blocked attempt to use history.pushState() Error

Hey everybody!

Today I tried to update my Website to Kirby 3.6
Everything works fine so far but I get a strange Error when I try to access the panel.
In my Console it says „Blocked attempt to use history.pushState() to change session history“ and then something with User and Password must mach.
The result is that the panel login page is just a white background and I can’t login.

I changed back to the version before and it works flawless again.

Any Idea how to fix this?
Does this maybe have something to do with the Kirby Catch files or file permissions?

Thank you!

Have you deleted the session folder, media folder, cache folder, cleared browser cache etc?

Thank you for your reply!

I deleted everything except the cache and session folder.
I’ll give it a try and tell you later if it worked.

Sadly it’s still not working.
Attached an Screenshot of the Error Message.

Thank you!

Where does this other URL with port 9258 come from?

Hey @texnixe

I really don’t know.
But I know that the URL with port :9258 is according to the phpinfo() log, the Server Host. So I think somehow Kirby is confused between the actual url and the host-ip-address.
Never got this Error Messege before the update to 3.6 so I think maybe it’s really a cache/session error. All cache/session files I have to delete are in the site/ folder right? Is there anything else I could have got forgotten?

Thank you!
