Failed to execute the [velocity] macro shown up after installed xwiki

I was very depressed that after I installed xwiki war (tomcat 8 with java8) all velocity-macro failed to execute. Says that:

Cause: [The execution of the [velocity] script macro is not allowed. Check the rights of its last author or the parameters if it's rendered from another script.].

org.xwiki.rendering.macro.MacroExecutionException: The execution of the [velocity] script macro is not allowed. Check the rights of its last author or the parameters if it's rendered from another script.
