Upload world / generating seeds

Hello there

Because the self-generated world in my server is just flat with some mountains, i wanna change.

So I followed many instructions that i could find to upload my world to my server. But when I upload a zip file, it just crash during the start up. I also tried to use generate but the map is still the same.

And then i decided to use plugin'manyworlds' to creat in-game new world using another seeds. But the weirdest is that the map is still the same (flat and bored). I even controlled the seeds of the map and it is indeed what i had put in.

Can someone help me? I dont want to play in a flat and bored map.

I just try it again for sure but as expected it is still the same😖

Hey

I've read the history start-up and found that my world format isnt supported by pocketmine-mc.

Is there any solution? I just wanna change my current world.

Thank you in advance

I forgot the attachment

Thank you for your answer. But do you have a solution to get another world? Because mine is always the same boring flat world.

I literally have no clue how to change it. I tried to make a new server/generating/using plugin to create new world. ~~

I just changed my software to bedrock and basically the server have indeed my seed.

So it means i cant select the seed in pocketmine?

Yea it is different even the world is dofferent with the same seed but basically whatever i change or do the world in pocketmine will be the same... Idk why
