I have change on doctorseyes.com the default browseer language from german (because our initial german page dentaleyepad.de was german) to english - it seemed to broke things regarding products. English products had spain langauge, some german - it was quite messed up.
Problem 2:
We really need to have the english langauge as the original and default language - so that by changing these products every other product will by changed accordingly - now its german langauge and it not just done by selecting a new default langauge.
Thank you for contacting WPML support, I'd be happy to help you with this issue.
