Hi Mert,
there are still some problems with translated text on some elements in the Workality Plus Theme. (example: http://ntown.at/2015/06/13/sensor-crop-factor-calculation-sheet/)
The developers from QTranslase-X has updated their plugin to work with other themes and plugins and integrated a configuration file for Themes.
Maybe you can take a look at this an suggest something to setup or config.

Thanks alot!
