Macros missing

All macros have completely disappeared. How do I recover these?

Have you deleted the user profile?

Where did you have your macros saved? The usual place is in MyMacros in the Standard Library. If you deleted your user profile, as @mariosv said, then they will have been deleted. When you backup your PC, as you should do regularly, make sure you include your LO user profile in the backup.

They were in the MyMacros location. Actually I don’t know how to save them anywhere else, or have any reason to. I have not deleted any user profiles.
Not the first time this has happened either.
