Pagination not working with qTranslate slug activated

Pagination of lists is not working with qTranslate slug activated. I may click con the any page number and it will always show the same pages. Try going back and forth here, https://casalista.com/blog/page/4/ or simply from the start: https://casalista.com/blog/. It will update the URL to https://casalista.com/blog/?paged=2, but not move on. I can update the URL manually to https://casalista.com/blog/page/4/, then it will go to page 4.

Something similar happens with pagination in categories. I classified my search here by the “consejos” category and this is placed as URL https://casalista.com/?cat=129. When going to the next page theURL changes to https://casalista.com/page/2/?cat=129, a page that not exists (goes to home page).

Note: the normal search works fine: https://casalista.com/?s=empleada&submit=Buscar will correctly switch pages, i.e. https://casalista.com/?s=empleada&submit=Buscar&paged=2

I tested it on some other sites and there this problem does not occur. The same is true for activating a standard WP theme (Twenty Fifteen Version 1.5). So the problem may be the Aloom theme we are using, but the theme provider (KIng Theme) insists on that it is a plugin problem and stopped replying to my emails or Skype messages.

Here is my set up:

WordPress Version 4.6.1 (es_ES) – also happened with previous versions
– Yoast SEO Version 3.5 – also happened with previous versions
– Integration: Yoast SEO & qTranslate-X = Version 1.2 – also happened with version 1.1.1.
– qTranslate-X version Version 3.4.8 – also happened with version 3.4.6.8
– qTranslate slug Version 1.1.18
