error code -50

[maccompaq]

When I try to empty the trash, I get a message: Cannot complete this operation, error code -50. I have spent hours looking on Google and Apple, getting several suggestions, but none work. I have used Terminal with no luck. I am using El Capitan.
Any help will be appreciated.

Have you tried all of the steps listed on this page?

You might give Trash It! a try as well.
