The ideal condition is while in route ‘/login/users’, showing ‘Please login first’. And after typing, if eamil or password is not suitable, showing ‘This email is not registered!’ or ‘Email or Password is incorrect. But, Not knowing how to make it work. The real condition only shows ‘Please login first’ on every condition above.
I try to rewrite req.flash(‘errors’) as req.flash(‘errors’, ‘ ‘). Error shows with two commas in the begining and the end. But it comes another problem: while in this route ‘/login/users’, Error seciton still shows with no content.
