BuddyPress.org

Hello,

I created my site in Dutch and then translated in English using wpml. For creating an account on buddypress I encounter the problem that the url-strings are made up as: https://domaine.com/?lang=en/pagename. But the strings on my site use the syntax: https://domaine.com/pagename/?lang=en. And so if users click the activation url in their mail they end up (by default) at the home-page because he doesn’t find that page.
Could you please explain to me in which file, and which part I can change the activate_url to make the url in the right syntax. And what would be the right syntax in that case.
Thank you so much in adavance,

Kind regards, Marieke
