Server won't load plugins right

So i installed the FTB ultimate reloaded server today, installed worldedit on it.
When i go ingame and do /sponge plugins, it only lists -Minecraft, -Minecraft Coder Pack, -SpongeAPI, -Sponge.
Altough worldedit is working perfectly fine.
I tried to install ClearLag as plugin as well, doesn’t show up, and doesnt work at all
Attached the Server log below, hopefully someone can help me.

From your log, you are using the Forge version of WorldEdit and not the plugin. Therefore it will show in the following command.

/Sponge mods

As for ClearLag. The file you downloaded isnt a plugin file. Begs the question. Where did you get it from?

[14:39:20] [Server thread/INFO] [FML]: FML has found a non-mod file Clearlag.jar in your mods directory. It will now be injected into your classpath. This could severe stability issues, it should be removed if possible.

ClearLag is a Bukkit plugin, right? Bukkit plugins don’t work on Sponge.

well i just found that out a sec ago xD
but thanks for the help

downloaded it directly from bukkit

didnt know there is a difference for bukkit and sponge, im very new to messing with stuff like this

but got it figured out
