New modpack! Need help!

[RiftRealms]

I created a thread earlier and Im too busy to close it as I had the issue fixed but now I re made it and I get the message "A fatal error has occurred, connection terminated" when joining my server. Heres the dropbox link our server/pack uses https://www.dropbox.com/s/lkxl6tr6mhvf7zg/modpack.zip?dl=0. Thanks for any help in advance that you can give. <3

You need to downgrade your vampirism mod version to the previous build (7.4.2 not 7.5) The author knows about this issue and stated he will release a fix for it in the coming week, so until that is released you will have to use the previous version. Also just a side note I noticed that you didn't include the config files in the modpack download, this can causes client connection issues if you change the server configs without updated the client ones, so you might wanna make sure those are included and updated.
