Host-Unlimited: Modded Minecraft Server - World-Generation is not working?

I put this question here, because I was in the not clear and insufficiently programmed forum host-Unlimited the possibility of asking questions.

Recently, I rented a Minecraft server from Host Unlimited. With some friends I wanted to start a small project with the "The 1.7.10 Project" from the Technic-Launcher. Now I downloaded the server data from the modpack, unpacked, executed and then moved via FileZilla to the server. Everything works, the server starts and there's no error message. My problem now is that the world generation does not play along. It will only create a 1.7.10 world without mods; Without ores, new biomes and structures created, making the game unplayable. I have already tried to create a world in the single player and then transfer it. What is created is a world in which some chunks are loaded around the spawn area with mods and then a cut between the biomes, where again the vanilla area is loaded.

I hope you can help me as soon as possible. As I said, there were no error messages.

And again one who fell for this unspeakable hoster.

Read here also other topics about HU… All have not good to announce…

I do not know why HU does not understand this and continues to provide such poor support (their servers are useless) - I also do not know why you all think cheap hosters can be good…

Many thanks for the answer. I have now decided for Nitrado.

A wise decision, because there you get all the support you need

Well xD
