I would try to add some listing first

I have, but not working.

and I have another question: where is direction of http protocols? cause I wanna change https

I solve this task. (http vs https)  file: config.php
But I have one bag with search, for ex.I have 2 types of languages Port. and Eng (if I search in Portuguese and use english phrases - results 0 ) and same with English type of site.

@emmvi
That is osclass.... if you enter title in english, in database there is nothing for Spanish version, therefore you cannot find it.
Languages are considered more as locales, not translations. Each language should represent 1 country.
