It seems that I am unable to translate the plugin strings using WPML despite it being listed on their compatibility page. Even though the WPML settings are correct, the strings do not show in the backend up for translation.
I opened a ticket with WPML if you wish to see the exact details of my problem. The thread end with them saying they will attempt to contact you and that I should do the same, so here I am :)
I came across this post from your support page and wondered if it was ever resolved?
I think all my versions of everything are outlined in the WPML ticket (basically everything is up to date) and I can send you the credentials to a test site I uploaded if you want/need to poke around.
Thank-you for any help you can offer.
