Hey, just another user struggling with making mods compatible. It's an utter pain going through each mod individually and deleting stuff until the server miraculously starts. I've already deleted 6 mods to no avail. I don't know how to read crash logs, so I might as well ask other people to do it for me.
I grabbed the log from the website (https://mclo.gs/TAYaOzq) as well as threw it in a pastebin just in case.
I can list the mods being used and I'll try to answer any questions. Please help, thanks in advance.
