Just installed Eventsbooking component on our site. It's in Swedish so I also uploaded the attached Swedish language file under the Joomla language folder.
But the language doesn't switch. It's still in english. I change to Swedish in the dropdownmenu at the Translation management panel but when I save, it changes back to english again.
Maybe something special on your site causing this issue . Could you please submit a support ticket sending us administrator account of your site so that we can check it for you ?
