Hi (yet again, sorry!)
I have a plugin called 'Business Directory Plugin' and it creates a directory on my wordpress blog. It works by using one shortcode and then it creates it's own pages from there.
If you try to translate on of the pages on that directory, it takes you back to the English version of the main page.
Take a look. Try translating the page and you'll see what I mean.
All help is much appreciated! Thanks!
