INCOMPATIBLE FML MODDED SERVER

[Sakke]

So i was running a LAN-server just fine for the past couple of days.
Today we started up the server but to our surprise nobody could join well they join and then instantly leave and just get the disconnected error in the launcher.
We both have the same version of the modpack which was oceanblock 1.6.0 and then both updated to 1.7.0 to see if that fixed it.
It says that the server is 'inompatible fml modded server' which if i understand correctly means the modlists are not the same.
Which is weird because we checked versions, i even copied my modsfolder and pasted it on the other computer.
And if i launch a different world from the same launcher just a blank new world he can join it no problem whatsoever.
I hope this makes sense if you would need any log files or any other information just ask.

Thanks in advance

If you guys upgraded to 1.7 from 1.6 I find sometimes the upgrade doesn't always works properly. I would simply attempt a clean install on the server (keep the world just new mods,config, kubejs, libraries, default config folder. Get the server files for 1.7 via FTB website), your PC and your friends PC. Try that and see if that helps
