The plugin seems to work fine for me, can you describe the problem or error log.

Its a plugin dependency with ZoneManager. I think if you restart the server it should work. make sure TruePVE and ZoneManager are the latest version
just tested DynamicPVP on my test server and it work

yes everything has already been done and nothing to do always the same

At the top of the plugin you need to have the //Requires to reference TruePVE or NextgenPVE
//Requires: TruePVE
//Requires: ZoneManager

my log looks like this: ( the debug message are not errors )
DynamicPVP, TruePVE and ZoneManager were compiled successfully in 2220ms

If you type o.plugins in console and the DynamicPVP plugin is loaded. then it is probably a configuration issue

This is what I get in console:

 DynamicPVP - Failed to compile: DynamicPVP.cs(223,18): error CS0117: `Facepunch.Pool' does not contain a definition for `Directory'​
