Actually it’s the jkreativ’s native wpml-config.xml.
But there are other major problems about creating multi-lingual site with jkreativ. You might have already tried on your side or it may be because of the pugins or misconfigurations on my side. But I’m having difficulties.
* Polylang doesn’t suit with portfolio. It turned the portfolio page blank. I mean portfolio items gives 404 errors when published. When draft no error but obviously it needs to be published to be seen on the front-end. WPML? No, problem.
* With both plugins the customisable texts in metaboxes can’t be changed. I saw this in full screen slider in landing slider and also in portfolio page category filter text.
