What is the problem?
When I send a print job from Cura (4.6.1) I get a message in Cura saying the printer is already printing, cannot select a new file. Everything prints fine.
I see the pop up Sending message, then the pop up Storing message, then the error pop up
What did you already try to solve it?
I haven't tried to solve it because printing works fine. It looks to be a communication issue between The Cura Octoprint pluding and the new 1.4.2 Octoprint. Cura has not prompted me to upgrade any plugins... that may resolve it when the plugin upgrades.
