Modpack crashing

hello!

I've recently tried installing mc eternal lite on my server and whenever I try to start the server it crashes, I've tried more than once and the same thing happens. Here's the log: https://mclo.gs/LxT0rf9

Thanks!

update: I just tried starting the server without using biomes o' plenty in the generated world and it did work, is there a possible way to fix the problem with biomes o' plenty or should I just continue without it?

Thanks in advance.

Another Update: So the server does still crash even if I don't use biomes o' plenty, not sure if it's the problem or not anymore. Thanks

Update: I tried loading the server from a different account, (since my friend and I were loading it from his account I tried from mine), and it worked.

PS: sorry for spamming so much updates, just trying to give as much info as I can, thanks.
