The Gtranslate PRO is changing the page and subpage language to random one even to language that is deactivated in the module. When clicking on the menu or other active links on the page the page is changing the language by itself. The URL sometimes looks like this: http://silverfin.pl/de/es/features.html
the page is written in polish and when walking through sub-pages they are, sometimes, displayed random other language. What is wrong? How to correct this problem?
