No, I want to get to the bottom of this. Why did you ask it on the forum if you ignored the correct answer and decided that you know better?

Next time check everything yourself multiple times before commenting or asking anything on the forum. If something like this happens again, you won't receive any help from me in future.
ok. sorry
Thanks to your answers solved my error. ACTUALLY WAS THE BACK-END
