The diodes are shorting the ouput of the opamp instead of clipping the signal. Connect a 1k resistor in series with the output coupling capacitor and the diodes.

Are you supposed to connect signal ground and power ground from the 9V battery together?
The source signal has a ground. If it is not connected then the circuit picks up mains hum.
The output signal has a ground.
All the grounds connect together.
The negative terminal of the 9V battery also connects to all the grounds.
