Server crashing after mod updates for FTB Unleashed

[PixelHunter89]

I was getting on FTB Unleashed and it told me there were some updates for a few of the mods. I updated them and then deleted all the server's old mods and replaced them with the newer ones. I also did the thing where i replaced the config folder. I tried starting my server and I got this:

I'm fairly new to all this so please help

 

[seriousvern]

it looks like you used the client side version of the pack instead of the server files. some mods are in client that are not need server side

Nevermind. I'm pretty sure i figured it out. Thanks

He would have uploaded the server files instead of the client files. If it was a 1.1.4 server, select 1.1.4 in the launcher and select download server.

Or just modify the URL on the server download page to http://www.creeperrepo.net/direct/F...modpacks^Unleashed^1_1_4^Unleashed-server.zip
