I'm having a problem which seems just like https://lodge.statamic.com/support/1939-possible-bug-1110-group-by-date-no-longe -- specifically, the entries get listed out but the {{grouped_date}} variable is always empty no matter what I put in the group_by_date parameter for entries:listing. Code identical to what is in the documentation for this feature is exercising the problem.
I tried re-downloading from my store link and re-installing, no change.
Any advice?
