uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.
uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.
Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock
uSkyBlock gives you a complete Skyblock foundation with island progression, deep customization, and a maintained open-source codebase you can build on long term.
Complete Skyblock gameplay. Build your server around islands, progression, challenges, and party play.
Deep customization. Shape the experience with focused configuration including challenge design, biome options, custom islands, and more.
Integrates with your server. Extend uSkyBlock through its public API and placeholder support so it fits cleanly into your server.

Are you using KCauldron aswell??
I tried to setup a server (which went ok) but when I added forge (1.7.10) to my client it kept crashing (before the singleplayer/multiplayer screen came up).
After trying 2 different versions, the latest and 1 before, both did same thing so gave up on forge.

probably because were not optimized for KCauldron, special with extra mod packs.

I presume you mean "multivere-core". The error for not finding a safe spawn location can be fixed by setting a new spawn, this is a minor error and is nothing to worry about.
Good job now you got it fixed.

Posted Jan 11, 2016Well, I guess I fixed it. Just... 1 Error, about Massivecore. What do I need to do to change?

The v6.x.x or v5.x.x is only for WorldEdit and WorldGuard, no other plugins (read the RED writing at the installation section).
For 1.8 servers you need Essentials vTeamCity. The Essentials that is available on bukkit is only for up to 1.7.x.
Essentials is not a depended plugin hens there are no links provided for it.
Multiverse-Netherportals is linked in the above page, either the released version or a link to the dev builds.

Alright, I got WE 6.1 and WorldGuard 6.1, I just don't know what essentials I need to use. Because I can't find a 6.x.x OR 5.x.x And the only MultiverseNetherPortals is 1.7

In that case you probably don't make use of our Nether Feature. But that is up to you ofcourse :)

The workaround isn't changing anything. It's just that the players go to the deep dark to go to the nether.

Creating worlds with MV will bring you trouble in the long term for uSkyblock plugin. Believe me, we been there, flatland and other issue's. You dont want to restart your world after players have created their islands
If need be you can rename the world in the config and restart the server, this will then create the worlds with the name you want.
Having your own "work around" it for making it work (temporally probably) will not be supported by us.

I created it with MV when uSkyBlock was installed. My "skyworld" is called "IslandWorld".
I have a work around for now though.

Are you trying to use an "old world" from an other plugin to use with ours?
Are you creating yourself the Nether world or do you let the plugin create it?
I cant find any "loading of" any of the depended plugins or the uSkyblock plugin loading itself in the log. I do see so many errors related to other things.
I dont have a setup for KCauldron myself so this is something I can't check.
Using names like"IslandWorld_nether" indicates to me it's from an other skyblock plugin. These worlds are not compatible with each other.
You probably need to delete these worlds and let the plugin create what it needs to create (including the plugin folders to make sure it's all setup right).

do you have an old world called "skyworld_nether" if so remove it from the server, rename it. Then restart server.
While at it make a screen shot of /usb version or post a full startup log.

To have the nether working both value's need to be able to be divided by 32. Both 300 and 350 can't be divided by this.
You can set it close to 9 x 32 = 288 or 10 x 32 = 320 and 11 x 32 = 352
This is for now the only way to get the nether working (all other numbers divided by 32 are of course possible too).
