Looks like something is breaking resource loading using the class loader, or has broken the default current working directory of the MC process - not a dynmap issue: need to talk to whichever plugin guys are breaking it (if that is the 'saber factions' plugin you mentioned, you'll need to talk to them). Other thing would be a file permissions issue - check if the plugins/dynmap/colorschemes directory exists and has the indicated files - if not, you'll probably need to reinstall (although, you can try zapping the version.txt file and restarting the server, in order to drive Dynmap to refresh its extracted files).

I use virtus host. a090m.virtushost.net:8123

False, webhost works...
User config error: 20.05 14:54:33 [Server] Server thread/ERROR [dynmap] Could not load colors 'default'

So, how i fix it?

Rename dynmap folder to something else.

I will try it, ty

Did not work

Then re-download dynmap jar cause I'm not getting a java.io.FileNotFoundException
