Call to a member function ready() on a non-object

Fatal error: Call to a member function ready() on a non-object in /.../wire/core/ProcessWire.php on line 386

the error above comes up when transfering a  ProcessWire 3.0.28  Setup from dev to live host. php version is 5.5.9
cleaning up cache folder and file-compiler cache or temporary emptying the /site/modules/ folder can`t resolve the issue. Any idea?

ok, seems to be ok with actual master 3.0.42
