Dear guys,
No error was found vs. No errors were found.
->Which one is correct?
Sometimes, I see “no errors were found” be used???why?
Tks in advance! 
Both are fine in any circumstance, but if you expected a lot of errors, use the plural; if you expected only one, use the singular.
Oh, thank you very much, I grasped it.
Wishing you good health, Mr Mister Micawber !
