Topic on Extension talk:Genealogy/Flow

I'm setting up a private wiki for family genealogy. Having trouble getting the #if to work.

My steps:

1. duplicate source code form the template:person on the demo site
2. installed all the parser extensions used on the demo site

My MW installation is

MediaWiki	1.38.2
PHP	7.4.30 (cgi-fcgi)
MySQL	8.0.30
ICU	69.1

Would be most grateful for your help.

Update: the #if behavior is strange, but I have some workarounds, primarily exclusion of the close }} tag at the end of the command. Doesn't make sense to me, but it works. Duplicating the person template on the demo site still doesn't work.
