duplicate content combining wordpress SEO and WPML

not sure whether that has to do with either plugin. Could it be that you have forgotten to reset your query on the fullwidth page template of your child theme?

I use a twenty twelve child theme. But if i deactivate my child theme and use only twenty twelve the problem continue. not only in my static front page.
Thank you for your help,

That is strange indeed.

Maybe a setting in WPML? I don’t see a language switcher in place. Have you by any chance duplicated your post and/or not set it to be a translation of the original?

To be able to say more instead of guessing at what it might be I would need access to your site.

in one column view pages there’s no other language switcher then the one in the footer.
Actualy I have only activated spanish language, but in a nearly future English and Catalanish will be accessible.
The conten is not duplicated. When i deactivate one of this two plugins the problem disappears.
if you like I can give you admin acces.

sure, you can contact me via the Consulting link on https://wpti.ps/

The problem is about the “Responsive Slider” plugin.
I deactivated this one and the problem disappears.

Thanks for all,
