Minecraft coordinates are not displayed (F3)?

Hey

When I play Minecraft and press F3, the coords don't show up. I mostly play with Lunar Client, Labymod or Optifine. With Labymod it's not that bad as I can display the coords manually. But when I play with OptiFine, the coords are not displayed. How do I reactivate it?

What does your debug screen look like? Can you add a picture, please?

OK wait

/ gamerule reducedDebugInfo false

I can't tell you exactly either, but take a look at the Minecraft settings to see how the key assignment is, maybe something is wrong

I have everything on standard, except for toggle perspective (i.e. F5). But I have F5 on C. So it can't be because of that.

OK

The server can issue that

Still not shown. But / gamerule just means that it can be seen in the world. Not everywhere, right?

I tried it in a world

But after all I need it everywhere

You can't do that

(Except with mods yk)

According to https://gaming.stackexchange.com/a/193498 there's a corresponding option in the game settings

You still have to show "reducedDebugInfo" in the chat settings
