There were slight bugs in the theme, but that was not the problem. It is listed as WPML Compatible while in fact it isn't. The support could assist for 2 weeks and I payed to 3rd party developer to make the logo change in each language (2 hours of work)...

Hello,
We located your support thread regarding this matter #1886438
Our Justicia theme and all others are compatible with 3 translation plugins. WPML, Polylang and Loco Translate. We never had any serious problems with them, nor we received any kind of urgent reports for things not working.
As far as we could see, our customer agent provided you with some sort of solution for your multilanguage website. We didn't receive any feedback from you ever since so we couldn't know if the solution was alright.
If you still have any further issues with our theme, please submit another ticket and our agents will gladly assist you. User's satisfaction is our main priority and we're doing our best to help you all out.
Thank you.
Mikado
