Hey. In your log it actually tells you whats goinf wrong.
java.lang.UnsupportedOperationException: SpongeCommon does not have it's own ecosystem, this needs to be mixed into for implementations depending on SpongeCommon
Its a little technical but the idea behind it is there is a plugin requesting the economy code section without checking if its there or not. So the way to fix this is to get an economy plugin
Wow… That is dumb… Also i do not want one…
What one should i use?
If you find out what plugin(s) are requesting it you maybe able to talk to their developers and have the issue sorted.
As for what eco plugin, it doesnt matter
