I’m facing an issue using sublime merge unable to checkout,commit,merge or any activity.
Do you have any additional details? Could you take some screenshots of the error response? Can you try the same actions on the command line to make sure it is a Sublime Merge specific issue?
If you click the icon to the left of where it says
failed: (with the on it), a popup will appear that shows what
git command was executed and what the actual error message is. That would help in diagnosing what the underlying problem is.
