Hello again,
I am currently using the non-plugin version of GTranslate Pro on a customer's site. It seems that some pages only get partially translated, e.g.
http://www.furthof-antikmoebel.de/en/abbeizen.html
Adding ?force_translation=1 helps, but I certainly do not want to do this on every page. Is there another way to get all pages translated completely? Something about limit.txt? Or does the customer need to buy a Google Translate API key?
