dark theme not working

Just tested on 9.5.8 and it works as expected

Go to Gin Settings, set Darkmode, hit Save.

Closing as I can't reproduce this.

it also works the first time.
I wanted to change something and then save it and with me it stays white theme instead of the dark theme.
I've done everything but nothing works.

i found problem.
it was rocket loafer from cloudflare which is problem.
