troubleshot
It must be admitted that this often sounds strange when used.
e.g.
Director: Have you sorted out those staffing problems in our West City branch yet?
Manager: Well actually, I troubleshot them all last week. What I did was ...
Unfortunately this sounds as if the Manager shot the workers! However, 'troubleshot' is, by reverse conjugation, the correct past form of troubleshoot, based on the past form of to shoot. And the past of shoot is shot, NOT shooted!
In view of the fact that the past form 'troubleshot' may sound peculiar, an alternative expression or synonym is often used.
e.g. Manager: Well, I actually sorted it all out (resolved the matter) last week. What I did was ...
