So I tried to create a server with about 60 different mods and then got this error java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityPlayerSP I really don't know what's causing this problem since I removed all client-side mods from the mods folder. Here's the server's crash report. ---- Minecraft Crash Report ---- WARNING: coremods are present: SecretRoomsMod-Core (Secret-Rooms-Mod-1.12.2.jar) midnight (themidnight-0.3.5.jar) MicdoodlePlugin (MicdoodleCore-1.12.2-4.0.2.238.jar) MalisisCorePlugin (MalisisCore-1.12.2.jar) Contact their authors BEFORE contacting forge // Daisy, daisy...

Hi, I am fairly new to Tekkit and recently found a modpack that I really enjoy. I'd like to play it with my friends sometime, but I am not sure how setting up a server with a public modpack works, or if you can do that. I would appreciate it if somebody could direct me to where I can find out how to set up a server with a public modpack, or if somebody could simply tell me that would be nice too. I apologize in advance if this isn't where this topic should go, or if this question has already been answered.

so i created an attack of the b team server, it worked fine nothing went wrong, then today i went to go on it and at first it said i had no connection to the server, so i refreshed a little and then finally it turned green and said i had connection, so i clicked join server, then it said "connection lost: Bad Login" what do i do, this hasnt happened before. i didnt see any other topics about this but i am really sorry if there is already one that could help me and this isnt just happening with my server, i tried to join a public b team server that i have also previously played on and it said the same thing, is it my serve ror the launcher or both? please help if you can.
