Can´t see a Astroprint tab


Hello, i installed the astroprint plugin via Octopi´s pluginmanager an i get the follwing informations from the pluginmanager:

“Installing collected packages: AstroPrint
Running install for AstroPrint: started
Running install for AstroPrint: finished with status ‘done’
Successfully installed AstroPrint-1.1.0
You are using pip version 9.0.3, however version 18.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip’ command.

After restart of the octopi-system, i can´t see the atroprint tab in my octopisystem, even though the system reports “Successfully installed AstroPrint-1.1.0”

I tryed the installation 5 times and i never was sucsessfully. I tryed to install other plug ins, such as “webcam” and “bed visualizer” and this was sucsessful.

Where could be the problem?

Thank you for you help.

Greetings René
