Hello,
In a new Joomla! 3.8.11 installation, only with Community Builder package and CB Field Groups 1.0 installed. I have created two text fields cb_team and cb_score. A new group field cb_group only containing previous fields, allways return white page with "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'json' at line 2" when I try to save it.
In front-end group is published and it looks work, but it crash when try to save with "1054 Unknown column 'cb_group' in 'field list' "
Some idea?
Thank you
José Martinez
