Shan you are my hero! 
I got it, i am able to see my own messages, although no data is shown, but doesn’t matter, it already works.
My mistake was:
https://www.media-junkie.com/http-test/_functions/filter <— wrong-way
https://www.media-junkie.com/_functions/filter <— the right one!!!
But now the question is, why it got no data out of my DB ?
