datapacks

Download your world or grab a world from somewhere and upload the datapack to it, then upload it to aternos.

And for in the future, i'd suggest using a translator

Also, make sure to do that when you start playing on that world, not a while after. Aternos has a 200MB upload limit

Also this post was from march the second.

Responding to it is pretty much useless

wow, it really is a month old... I did not see that -_-'

Although last time I tried, I'm sure it said 200MB... did it change since January?

Changed on January 22th. Yes.
