(Wrong section)

On topic, the error is caused by MCore. It's searching for a class which does not exist. You should wait for the developer to update their plugin and hopefully fix the bug.

 

Yep this is because it needs updating.
And this also isn't plugin development

 

Moved to the correct forum.

 

I also have this problem, we need to wait till de developer releases the 1.6 version...

 

I am having the same problem anyone else running their server on a mac?

 

im running on mac
and i have the same problem

 

ME to id dosnt work for somereason?

Hey! I'm having trouble too, i'm not sure if its the same problem though. I have installed different jars, and they all just sit in my folder and do nothing. if i do /plugins, it doesn't show up, is anyone else having these problems? Or should i seek help elsewere

 

It's probably for the best...
