I am using matplotlib & bottle.py to plot a graph, based on an input value on my webpage:
when I am logged into pythonanywhere, the plot displays. But when I am logged out, I just see "image placeholder". The plot is a .png image, and seems to be readable by everyone.
In the error log, I do see:
OSError: write error 2017-11-28 14:15:13,247: Error running WSGI application 2017-11-28 14:15:13,267: GeneratorExit
Does anyone know why this might be occurring?
