I bit the bullet and upgraded the Mac Mini to Mavericks.
Now none of the refreshing URLs work on my control pages (they are all gnuplot PNG outputs).
My log file is full of: urlopen error (61, 'Connection refused').
I'm assuming this is because Web Sharing has been removed from Mavericks?
Anyone else who regularly loads image files via refreshing URLs, how did you get around this when 'upgrading' to Mavericks?
Sam.
