Tabs stop working in subpages

After updating Kirby to the latest version tabs inside subpages stops works

when I open the page directly via URL tabs is open but for some reason in Kirby panel tabs are not open.
for pages, first-level tabs work well.

can you help me with this issue?

for now, find only one solution change it via htaccess

RewriteEngine on
RewriteCond %{THE_REQUEST} %2b
RewriteRule ^(.+)$ %{REQUEST_URI} [R=301,L,QSA,NE]

Hi, I got the same error. Is this a bug in Kirby? The above solution feels more like an emergency solution.

The tabs works locally but not on staging for me.

Environment local:
Kirby: v3.6.5 (same in v.3.6.2)
PHP: v7.4.16
Server: Nginx

Environment staging:
Kirby: v3.6.5 (same in v.3.6.2)
PHP: v8.0.17
Server: LiteSpeed

I think this is a bug in Kirby.

I was trying to recreate the problem with tabs in Starterkit. The only thing I changed was that I added tabs in the note blueprint. And then comes the error.

Test environment:
Kirby: v3.6.5
PHP: v8.0.17
Server: LiteSpeed

I dont think this topic has been solved.

I just recreated your setup in the starter kit and on an apache server everything is working just fine.
So I suspect it must have something to do with the LiteSpeed server

Yes, and everything is working just fine on nginx as well.
So it seem to be related to LiteSpeed.

Did you change htaccess as I wrote?

Yes I did and it works. The client can continue working because of your snippet, thanks! But it does not feel like a solution over time to have to edit .htaccess because you using LiteSpeed as your server.

Sure, will wait for official fix

One day, even this solution stops working. So I investigate other variants and found this one

    header("Location: ".strtr($_SERVER['REQUEST_URI'],array('%2b'=>'+','%2B'=>'+')));

Only one thing I don’t know is it solution is safe for XSS
