Gazebo not following the path generated

Hello, I'm very new to ros, gazebo and rviz etc.
I succesfully compiled the project. I can do plan the path in rviz.
However, when i execute the planned path generated, the quadrotor in gazebo is not follwoing the path generated.
I'm not sure why ...

Is the quadrotor not moving at all or the path executed is not the correct one?

Hello @AlessioTonioni ,
Thanks for your reply,
The quadrotor is not moving at the first place, so i set the execution_duration_monitoring value to "false". Now, the quadrotor moved, but it does not follow the path executed.

i get this error when running the 1st script:

Error [Plugin.hh:156] Failed to load plugin libgazebo_ros_controller_manager.so: libgazebo_ros_controller_manager.so: cannot open shared object file: No such file or directory
Warning [gazebo_quadrotor_simple_controller.cpp:57] The GazeboQuadrotorSimpleController plugin is DEPRECATED in ROS hydro. Please use the twist_controller in package hector_quadrotor_controller instead.

does it cause the error that i am facing now?

Hi,
Yes i think that the missing plugin could be the problem, take a look at this question:
