Hi @arminunruh !
I'm having an issue on a client site, where suddenly on edited or newly created pages qtranslate text content gets shown duplicated (both languages at the same time) in the preview/live version. It looks fine in the gridder.
See an example here: https://feedmelab.pl/en/category/ilya-bohdanovich/
I already updated qtranslate to the latest version from their github (3.15.5), but the issue is still there.
All previously created posts look fine, the issue appeared recently and affects only new and edited pages (categories in this case).
Could you please help? Thank you!
