Column 'parentId' in where clause is ambiguous - Statistics
Hi Bob (sorry, still trying to find time to get to your other post ;)
That rings a bell and has been fixed a while ago, in https://gitlab.com/tikiwiki/tiki/-/commit/4f17e282 but looks like it never got backported to 21.x - oops!
Ok, done in https://gitlab.com/tikiwiki/tiki/-/commit/dba35079 (thanks for the reminder, shame it wasn't in time for 21.3 )
