What is the problem?
old plugin CuraEngine Legacy installed - can not close and uninstall it
Have you tried running in safe mode?
yes i have the entry " server: startOnceInSafeMode: true" in config.yaml - the window still comes up
Did running in safe mode solve the problem?
No . see aswer bevor
I installed the CuraEngine Legacy plugin because I thought it would work with the current version of Octoprint. Now this remote window "hangs" in the foreground and I can no longer get into the PluginManager (or anywhere else) to get rid of this stupid plugin. Is there a way to remove this plugin also via Putty?
