Thank you for reply. I used KCauldron-1.7.10-1517.166 which is 2 versions back and I am getting the same thing as before. The log looks exactly the same. I will try and older version beyond that if you would like to provide a version # you know is working.
I did search Google and found this, but I am not sure on exactly what to look for.
I ran the server without Kcauldron and it look to come up. I could not access it from minecraft (another issue altogether). When i added Kcauldron back it failed like the issue above. This was with 2 separate versions of Kcauldron.
The second link has instructions to fix the issue. If that doesn't work, Infinity evolved uses Forge 1448 so I'd try a kcauldron version that uses the same Forge version.
Do you have any automated tasks that should execute any commands?
