I deleted all profile fields, set new profile fields in 2 groups: Base (Primary) and Company.
Now Company field group is not showing in the Profile page, and Base fields generate the same error when save changes is clicked.
Plugin disabled: BP Profile Shortcodes Extra (generated many errors including fatal error)
Plugin active: BuddyPress Xprofile Custom Field Types
Is there proven tutorial how to successfully add more fields in BP Profile?
